| In the Linux kernel, the following vulnerability has been resolved:
NFSD: remove flawed WARN_ON_ONCE from nfsd_mode_check
The header for commit e75b23f9e323 ("nfsd: check d_can_lookup in
fh_verify of directories") details the assumption that justified
adding the WARN_ON_ONCE to nfsd_mode_check(), that assumption is
invalid (in the case of NFS reexport).
When NFSD exports an NFS filesystem it is very possible for
nfsd_mode_check() to encounter a @dentry that doesn't have
i_op->lookup (see nfs_fhget()'s NFS_ATTR_FATTR_MOUNTPOINT and
NFS_ATTR_FATTR_V4_REFERRAL handling, and d_flags_for_inode()).
So remove nfsd_mode_check()'s WARN_ON_ONCE(). The nfserr_notdir
return on that branch must stay. It guards the subsequent
lookup_one_unlocked() -> __lookup_slow() path, which calls
inode->i_op->lookup() with no NULL check, so returning nfserr_notdir
is what keeps a client LOOKUP into such a @dentry from dereferencing
a NULL method pointer. |
| A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured BGP neighbor to cause a denial of service via a BGP route update when specific routing-policy resolution-map and policy event-tracing configuration is enabled. |
| A NULL Pointer Dereference vulnerability in the rpd routing daemon of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated configured BGP peer to cause a denial of service via a BGP UPDATE when ISO-VPN and egress-protection configuration is enabled. |
| Null pointer dereference in Windows Schannel allows an authorized attacker to elevate privileges locally. |
| FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the client video redirection channel that allows malicious servers to crash clients by sending out-of-order messages. Attackers can send a Geometry CLEAR message that nulls presentation->geometry, then send VideoData that dereferences it, causing client denial of service. |
| Null pointer dereference in Active Directory Domain Services allows an authorized attacker to deny service over a network. |
| Null pointer dereference in Windows DHCP Server allows an unauthorized attacker to deny service over a network. |
| Lychee is a free, open-source photo-management tool. Prior to 7.7.1, the Supporter or Pro webshop POST /api/v2/Shop/Checkout/Process flow accepts an unrestricted additional_data array and CheckoutService::preparePurchaseParameters() merges it after server-computed purchase parameters. Because later string keys overwrite earlier keys, an unauthenticated buyer can replace amount, currency, returnUrl, cancelUrl, or transactionId before CheckoutService::processPayment() passes the parameters to a non-PayPal Omnipay gateway. An attacker can therefore make a gateway accept a successful payment for an attacker-selected amount and obtain auto-fulfilled goods while underpaying the merchant. The issue requires an enabled webshop, a purchasable item, and an affected Omnipay gateway. This issue is fixed in version 7.7.1. |
| Null pointer dereference in Windows Installer allows an authorized attacker to elevate privileges locally. |
| InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates. Prior to version 2.4.0, InvoiceShelf invoice, estimate, and recurring-invoice creation paths accept client-supplied total, sub_total, tax, discount_val, and due_amount values without verifying that they match the submitted line items. An authenticated user can persist manipulated financial totals through InvoicesRequest::getInvoicePayload and the corresponding EstimatesRequest and RecurringInvoiceRequest handlers, causing stored document totals to disagree with their item prices and quantities. This issue is fixed in version 2.4.0. |
| A NULL pointer dereference vulnerability has been reported to affect File Station 5. If a remote attacker gains a user account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack.
We have already fixed the vulnerability in the following version:
File Station 5 5.5.6.5243 and later |
| Null pointer dereference in Windows Message Queuing Queue Manager allows an authorized attacker to deny service over a network. |
| mp4v2 2.0.0 contains a NULL pointer dereference vulnerability in MP4File::GenerateTracks() in src/mp4file.cpp. This allows a remote attacker to cause a denial of service |
| A NULL Pointer Dereference vulnerability in the DNS plugin of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS).
When multiple DNS queries are received in a single flow session, where one query matches a Security Intelligence (SecIntel) feed and another query is sent for DNS Domain Generation Algorithm (DGA) analysis, an error in processing logging of these asynchronous tasks can lead to an FPC crash. The exact timing conditions are outside an attacker's direct control.
This issue affects Junos OS on SRX Series:
* All versions before 23.2R2-S7.7;
* from 23.4 before 23.4R2-S8.13;
* from 24.2 before 24.2R2-S5.5;
* from 24.4 before 24.4R2-S4;
* from 25.2 before 25.2R2-S1;
* from 25.4 before 25.4R1-S2. |
| Null pointer dereference in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to execute code locally. |
| A NULL Pointer Dereference vulnerability in the rpd process of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker to cause a denial of service via a malformed RSVP Path message received on an EVPL LMP control channel. |
| A NULL Pointer Dereference vulnerability in the rpd routing daemon of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to crash the routing daemon and cause a denial of service via an RSVP Path message. |
| A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a remote unauthenticated BGP peer to cause a denial of service via a specific BGP FlowSpec update received by an affected BGP session. |
| A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated remote BGP neighbor to cause a denial of service via a VPN-flowspec BGP update if it is readvertised and BMP post-policy RIB-out monitoring is configured. |
| A NULL Pointer Dereference vulnerability in the na-grpcd process of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker with access to the chassis-internal network to cause a denial of service via a network message. |
