The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c.

CVE-2019-5188 7 Canonical, Debian, E2fsprogs Project and 4 more 10 Ubuntu Linux, Debian Linux, E2fsprogs and 7 more 2026-10-14 7.5 High
A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
CVE-2019-5094 6 Canonical, Debian, E2fsprogs Project and 3 more 8 Ubuntu Linux, Debian Linux, E2fsprogs and 5 more 2026-10-14 7.5 High
An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
CVE-2019-3863 5 Debian, Libssh2, Netapp and 2 more 15 Debian Linux, Libssh2, Ontap Select Deploy Administration Utility and 12 more 2026-10-14 N/A
A flaw was found in libssh2 before 1.8.1 creating a vulnerability on the SSH client side. A server could send a multiple keyboard interactive response messages whose total length are greater than unsigned char max characters. This value is used by the SSH client as an index to copy memory causing in an out of bounds memory write error.
CVE-2019-3857 7 Debian, Fedoraproject, Libssh2 and 4 more 17 Debian Linux, Fedora, Libssh2 and 14 more 2026-10-14 8.8 High
An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way SSH_MSG_CHANNEL_REQUEST packets with an exit signal are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-3856 7 Debian, Fedoraproject, Libssh2 and 4 more 17 Debian Linux, Fedora, Libssh2 and 14 more 2026-10-14 8.8 High
An integer overflow flaw, which could lead to an out of bounds write, was discovered in libssh2 before 1.8.1 in the way keyboard prompt requests are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-3855 8 Apple, Debian, Fedoraproject and 5 more 18 Xcode, Debian Linux, Fedora and 15 more 2026-10-14 8.8 High
An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
CVE-2019-18348 2 Python, Redhat 2 Python, Rhel Software Collections 2026-10-14 5.4 Medium
An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the host component of a URL) followed by an HTTP header. This is similar to the CVE-2019-9740 query string issue and the CVE-2019-9947 path string issue. (This is not exploitable when glibc has CVE-2016-10739 fixed.). This is fixed in: v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1; v3.6.11, v3.6.11rc1, v3.6.12; v3.7.8, v3.7.8rc1, v3.7.9; v3.8.3, v3.8.3rc1, v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1.
CVE-2019-18224 2 Gnu, Redhat 2 Libidn2, Enterprise Linux 2026-10-14 9.8 Critical
idn2_to_ascii_4i in lib/lookup.c in GNU libidn2 before 2.1.1 has a heap-based buffer overflow via a long domain string.
CVE-2019-17543 1 Lz4 Project 1 Lz4 2026-10-14 8.1 High
LZ4 before 1.9.2 has a heap-based buffer overflow in LZ4_write32 (related to LZ4_compress_destSize), affecting applications that call LZ4_compress_fast with a large input. (This issue can also lead to data corruption.) NOTE: the vendor states "only a few specific / uncommon usages of the API are at risk."
CVE-2019-15903 3 Libexpat Project, Python, Redhat 5 Libexpat, Python, Enterprise Linux and 2 more 2026-10-14 6.5 Medium
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
