| Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Camel FTP component.
This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1.
The Camel remote-file consumers poll a directory on a remote server and build the absolute remote path of each file by concatenating the configured directory with the file name reported in the server's directory listing. That concatenation (FtpUtils.absoluteFilePath and GenericFileConsumer) applied no lexical normalization and no check that the result stayed inside the directory being polled, and the resulting path became the operand for every subsequent remote operation on the file: retrieval (FtpOperations.retrieveFile / SftpOperations, reached from GenericFileConsumer where the retrieve name is taken verbatim from GenericFile.getAbsoluteFilePath), deletion when delete=true (GenericFileDeleteProcessStrategy), and renaming when move, preMove, moveFailed or readLock=rename is configured (GenericFileProcessStrategySupport and GenericFileRenameExclusiveReadLockStrategy). Neither isValidFile nor isMatched performed any containment check. A listing entry that is not a single path segment therefore resolved to a path outside the configured polling directory, causing Camel to read, delete or rename files outside it using the endpoint's own credentials. A listing name is not route-controlled data. It is supplied by the remote server, and the FTP control channel carries no integrity protection at all, so an on-path attacker can rewrite a LIST response without holding any credentials; a compromised, malicious or multi-tenant server, or a server backed by a virtual filesystem, can emit such a name directly. Retrieval is reachable in a default consumer configuration, since the remote consumers download every listed file; deletion and renaming additionally require one of the disposition options above, all of which are common. Escape from the directory Camel was configured to poll is unconditional, while escape from the server's own account boundary additionally depends on whether that server confines the account. The jailStartingDirectory option, which is documented as restricting Camel to the starting directory and is enabled by default, governed producer writes and, since the localWorkDirectory containment work, consumer downloads to the local work directory - but it did not constrain this remote operand, so its name and description claimed a boundary that was not enforced here. The same entry point had already been recognised on the local side: the localWorkDirectory download path was constrained so that a remote file name containing parent-directory segments could not resolve outside the local work directory. The remote operand was the remaining half of that surface. This artifact provides the ftp, ftps and sftp schemes, all of which are affected. The reporter demonstrated the issue end to end against an ftp endpoint, driving a Camel route with a malicious server whose LIST response named a file outside the polled directory.
Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.22.x releases stream should upgrade to 4.22.1. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. The 4.14.x stream reached end of life and does not receive this fix; users on it should move to a supported releases stream. |
| Cesanta Mongoose before 7.22 contains an out-of-bounds read in the built-in TLS server function mg_tls_server_recv_hello(), which uses an attacker-controlled session_id_len byte from a TLS ClientHello as a buffer index without validating it against the length of received data. A remote, unauthenticated attacker can send a single crafted ClientHello with an oversized session id length to read past the receive buffer, crashing any HTTPS, MQTTS, or WSS service built on MG_TLS_BUILTIN. |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. |
| TinyUSB before 0.20.1 contains an integer underflow vulnerability in the HID host report descriptor parser tuh_hid_parse_report_descriptor() in src/class/hid/hid_host.c that allows a malicious USB device to trigger an out-of-bounds read by subtracting an item size from the remaining descriptor length without validating the item fits within the remaining buffer. Attackers can present a crafted USB device with a truncated report descriptor causing the uint16_t desc_len value to underflow, resulting in out-of-bounds memory reads and denial of service on the host system. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring/waitid: prevent cancel reference wrap
io_waitid packs the cancellation state into bit 31 of ->refs and uses
bits 30:0 as a 31-bit reference counter:
#define IO_WAITID_CANCEL_FLAG BIT(31)
#define IO_WAITID_REF_MASK GENMASK(30, 0)
__io_waitid_cancel() marks a request canceled, then increments the low
bits of ->refs to claim completion ownership. When another path owns the
request, the increment remains even though cancellation returns false.
The request remains discoverable by cancellation, so repeated failed
attempts can wrap the 31-bit reference field to zero. A later
cancellation can claim ownership and complete the request a second time.
Use atomic_fetch_or() when setting the cancel flag and inspect the old
flag value. The first cancel attempt continues to the existing ownership
increment, preserving its wake and issuer handoff semantics. Later
attempts see the cancel flag and return without incrementing the
reference field.
This makes repeated failed cancellation attempts idempotent while
leaving the first-cancel state transitions unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
keys: Avoid the owner account dereference in named keyring lookup
Named keyring lookup must keep the storage containing the owner UID
alive through the namespace mapping check. find_keyring_by_name()
reads keyring->user->uid under keyring_name_lock, but that lock protects
the keyring's name entry and allocation, not its separate key_user.
A named session-keyring join can overlap a privileged KEYCTL_CHOWN on
another CPU. If the keyring holds the last reference to its old dynamic
key_user and the ownership transfer succeeds, the following ordering is
possible:
Named join Chown
find_keyring_by_name() keyctl_chown_key()
read_lock(keyring_name_lock) down_write(key->sem)
load old keyring->user
replace key->user and key->uid
up_write(key->sem)
key_put(key)
key_user_put(old user): free
read old user->uid
read_unlock(keyring_name_lock)
Chown neither takes keyring_name_lock nor key_session_mutex, so it can
free the old account between the pointer load and the UID read. The
lookup then reads freed memory even though the keyring itself is alive.
Use keyring->uid for the mapping check. key_alloc() initializes this
inline owner UID and keyctl_chown_key() updates it on chown.
The existing name lock keeps its containing keyring allocated throughout
the check, so lookup no longer depends on the account's lifetime. This
also matches the owner UID used by the permission check.

| In the Linux kernel, the following vulnerability has been resolved:
keys: Check the authorization payload in process keyring searches
An authorization payload and its saved credentials must remain valid
while search_process_keyrings_rcu() searches the requestor's keyrings.
The function validates the authorization key, then separately loads
payload.data[0] and unconditionally reads rka->cred. Validation does
not prevent request_key_auth_revoke() from clearing the payload.
A request-key helper can assume authority and fork a descendant that
inherits the authorization key. If the descendant misses in its own
keyrings, it falls back to the saved requestor credentials. Successful
target instantiation invalidates the authorization key without clearing
the payload. After the helper exits, UMH_WAIT_PROC returns to the
requester, which calls complete_request_key() and revokes that key.
With the descendant paused after validation, the paths can interleave
as follows:
1. The descendant enters search_process_keyrings_rcu() under RCU and
key_validate() succeeds.
2. The helper instantiates the target, invalidates the authorization
key, and exits.
3. The requester resumes from UMH_WAIT_PROC, calls
complete_request_key(), and revokes the authorization key.
request_key_auth_revoke() sets its payload pointer to NULL.
4. The descendant loads NULL and dereferences rka->cred.
This NULL dereference can oops the kernel. RCU delays payload disposal
but does not prevent the pointer from being cleared.
Load the payload with dereference_key_rcu() and require a non-NULL
result before validating the authorization key and searching its saved
credentials. A non-NULL payload and its credentials remain alive for
the caller's RCU read-side section; a cleared payload skips the fallback
search and follows the existing error selection.

| In the Linux kernel, the following vulnerability has been resolved:
keys: Protect the type name while describing a key
keyctl_describe_key() must keep the key type's name alive until
kasprintf() has consumed it. The retained key reference keeps the key
and its description alive, but does not pin the module providing its
type. The name is passed to kasprintf() without holding key->sem.
kvasprintf() uses the saved name pointer in two formatting passes, with
a GFP_KERNEL allocation between them. With AF_RXRPC=m, a task that
passes View permission before type retirement can overlap a privileged
module unload in this order:
1. KEYCTL_DESCRIBE looks up the key, saves key->type->name in the
kasprintf() arguments and completes the first formatting pass.
2. While the formatter is delayed before its second pass,
af_rxrpc_exit() calls unregister_key_type(), which removes the type
from the registry and waits for key_gc_keytype().
3. The collector takes key->sem for writing, retypes the retained key
to key_type_dead and completes retirement. Unregistration and module
exit return, allowing free_module() to release the type and name.
4. The formatter resumes its second pass and reads the saved name from
released module storage, which can fault in string().
Hold key->sem for reading across kasprintf(). The collector then cannot
retype the key or complete retirement until both formatting passes have
finished. If retirement wins the lock first, formatting uses the core
key_type_dead name instead. Release the semaphore immediately after
kasprintf(), including on allocation failure, before copying to
userspace.

| In the Linux kernel, the following vulnerability has been resolved:
keys: make keyring indexes independent of kernel addresses
KEYCTL_READ returns the serial numbers in a keyring in associative-array
traversal order. The first word of the index is a public, deterministic
hash of the type pointer, domain pointer and description. An unprivileged
user can therefore insert keys with known descriptions, predict their
order for each possible KASLR slide, and recover the kernel image address.
On an x86-64 build with 16 MiB alignment, 45 user keys suffice to
distinguish the candidate slides.
Remove the addresses from the whole index, not just its first hash word.
Assign each key type and domain a nonzero 64-bit ID and hash those IDs and
the description with a once-initialized SipHash key. Use the full IDs in
the later index chunks as well. Truncating or hashing the IDs there would
lose the guarantee that distinct type/domain/description tuples have a
differing index bit.
Allocate IDs lazily since private key types need not be registered. Cache
them in the index key so tree walks and copies of an existing index do not
need to dereference a type descriptor that may have been unregistered.
Keep the 32-bit chunk layout and diff_objects() bit offsets consistent,
and retain the separate root slot for keyrings used by recursive search.
The key comparison, permissions and userspace data format are unchanged;
only the address-dependent in-memory ordering is replaced. |
| In the Linux kernel, the following vulnerability has been resolved:
keys: Protect the read method check against type removal
keyctl_read_key() checks key->type->read without holding key->sem.
A reference keeps the key alive, but does not pin the module containing
its type. A surviving RxRPC key can therefore be read while AF_RXRPC
is being unloaded:
KEYCTL_READ task Module unload and key GC
---------------- ------------------------
lookup_user_key()
permission / possession checks
load key->type
af_rxrpc_exit()
unregister_key_type()
GC: down_write(key->sem)
GC: retype to key_type_dead
GC: up_write(key->sem)
unregister_key_type() returns
free_module()
read saved type's read member
The final access can read freed module storage. The read invocation in
__keyctl_read_key() is already protected by key->sem, but the earlier
method check is outside that critical section.
Move the method check into __keyctl_read_key(), after key_validate() and
under its existing read hold on key->sem. The check and invocation then
use the same protected type for length queries and every read retry.
The GC cannot retype the key until the semaphore is released, and type
unregistration waits for that GC pass before the module can be freed.
Return -EOPNOTSUPP when validation succeeds and the type has no read
method. A temporary buffer may now be allocated before this result;
allocation and copying to userspace remain outside the semaphore. |
| In the Linux kernel, the following vulnerability has been resolved:
keys/trusted_keys: return immediately after TPM unseal failure
trusted_tpm_unseal() proceeds to pcrlock() when the TPM unseal operation
fails. If pcrlock() succeeds, its return value overwrites the unseal error,
causing key instantiation to succeed.
Return immediately when unseal fails to preserve the original error. |
| In the Linux kernel, the following vulnerability has been resolved:
asymmetric_keys: reject trust keys without IDs
The PKCS#8 parser deliberately leaves the asym_key_ids payload slot
empty. key_or_keyring_common() unconditionally dereferences that slot
when a PKCS#8 key is supplied to a key_or_keyring restriction. Both the
plain and :chain forms reach this branch, allowing an unprivileged caller
to trigger a NULL pointer dereference through KEYCTL_RESTRICT_KEYRING
followed by add_key().

ftrace: Initialize modname and offset in print_rec()
print_rec() leaves 'modname' and 'offset' uninitialized and
kallsyms_lookup() only sets them on success. When the lookup fails like
when a module is being loaded or unloaded, 'modname' holds a garbage
value, passes the 'if (modname)' check, and is dereferenced by
seq_printf().

coredump: hold RCU while releasing parked threads
coredump_finish() releases the parked threads by clearing ->task in
their core_thread entry and calling wake_up_process() on each of them.
It does that without holding a reference on the task and without being
inside rcu.
But calling wake_up_process(task) without rcu here isn't safe. A parked
thread doesn't need that wakeup to leave. A spurious wakeup or a
preemption after the store is enough for the task to go away.
So if the coredump client is preempted between the store and
wake_up_process() the thread can exit and be freed in the meantime and
try_to_wake_up() takes pi_lock in freed memory.
Hold rcu across the loop. |

| zt-zip is a Java library that provides convenience methods for ZIP archive manipulation. Prior to 1.18.1, ZipUtil.unpack(...) can apply stored ZIP-entry permissions to the extraction output directory when an entry name such as / or ./ resolves to that directory itself. Because the path traversal checks permit self-referencing entries that do not escape the destination, the unpacker's permission-handling path can replace restrictive output-directory permissions with attacker-supplied permissions. This affects applications that unpack untrusted ZIP files, and POSIX systems demonstrate the issue directly, while ZTFilePermissionsUtil.fetchDefaultStrategy provides fallback permission handling on other supported systems. This issue is fixed in version 1.18.1. |
| fastapi-code-generator creates FastAPI applications from OpenAPI files. Prior to 0.8.1, the generator inserts Operation.summary into a generated route-handler docstring as a triple-double-quoted string without escaping embedded triple quotes. An attacker-controlled or attacker-influenced operation summary can close the docstring and inject a valid Python expression statement into the handler body. Syntax-breaking input only causes generation to fail, but syntactically valid generated code executes with the server process's privileges when the affected route handler is called. This call-time route-handler docstring sink is distinct from the project's separate import-time route-path and additional-response-key sinks. This issue is fixed in version 0.8.1. |
| traQ is a messenger application built for Digital Creators Club traP. Prior to 3.28.3, OAuth2 silent authorization requests using prompt=none with an empty or omitted scope parameter check prior consent against the empty requested scope set even though all scopes registered for the client become eligible for issuance. An attacker who controls an OAuth client capable of receiving authorization codes can target a user who previously consented to only some client scopes and obtain an access token containing broader registered scopes without additional consent. A user who has never consented to the client still receives consent_required. This issue is fixed in version 3.28.3. |
