Astra Linux – Vulnerability in glibc

The wordexp function in the GNU C Library also known as glibc, up to version 2.33, may crash or access arbitrary memory during the parseparam function located in posix/wordexp.c when called with an untrusted, crafted pattern. This could potentially lead to a denial of service or the disclosure of...

Converting crafted EUC JISX0213 input to UCS-4 or the internal wide character encoding, for example with iconv, in the GNU C Library version 2.3 to 2.44 may result in the converter making no progress, causing the calling application to hang. Some EUC JISX0213 sequences decode to two code points. ...

K000163028: glibc vulnerability CVE-2025-15281

Security Advisory Description Calling wordexp with WRDEREUSE in conjunction with WRDEAPPEND in the GNU C Library version 2.0 to version 2.42 may cause the interface to return uninitialized memory in the wewordv member, which on subsequent calls to wordfree may abort the process. CVE-2025-15281...

TencentOS Server 4: glibc (TSSA-2026:0850)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0850 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

PT-2026-86427

Calling strfmon and strfmon l in the GNU C Library version 2.38 to 2.44 can write past the end of the caller-supplied output buffer when a conversion uses right-justified width padding. Exploitation requires an application code path that calls strfmon or strfmon l with right-justified width paddi...

Astra Linux – Vulnerability in glibc

Using wordexp with WRDEREUSE in conjunction with WRDEAPPEND in the GNU C Library, from version 2.0 to version 2.42, may cause the interface to return uninitialized memory in the wewordv member. This could lead to the process being aborted upon subsequent calls to wordfree...

PT-2026-84878

Calling tdelete on a sufficiently deep tree in the GNU C Library version 2.1 to 2.44 may write one pointer past the end of an alloca-allocated array on the stack, which may crash the application. The tdelete implementation keeps an explicit stack of parent nodes for rebalancing, which is grown as...

SUSE CVE-2026-6368

Calling wordexp with WRDEAPPEND in the GNU C Library version 2.0 to version 2.43 can cause the interface to return invalid memory in the wewordv member, which on subsequent calls to wordfree may abort the process...

SUSE CVE-2026-6791

When expanding paths that begin with a tilde followed by a username, the internal parsetilde function extracts the username to determine the user's home directory. The implementation allocates memory for this username directly on the stack using the strndupa macro. Because the size of this...

CVE-2026-6368

A flaw was found in glibc GNU C Library. A local attacker or application using the wordexp function with the WRDEAPPEND flag can trigger the interface to return invalid memory in the wewordv member. This invalid memory, when subsequently processed by wordfree, may cause the process to abort,...

CVE-2026-6791

A flaw was found in glibc. When processing paths that start with a tilde followed by a username, the wordexp function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhausti...

Linux Distros Unpatched Vulnerability : CVE-2026-6368

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Calling wordexp with WRDEAPPEND in the GNU C Library version 2.0 to version 2.43 can cause the interface to return invalid memory in the wewordv member, which o...
