CVE-2026-77117 SHIFT_JISX0213 decoding may hang on crafted input

Converting crafted SHIFTJISX0213 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 SHIFTJISX0213 sequences decode to two code points...

AZL-100968 CVE-2026-19542 affecting package glibc 2.38-21

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...

AZL-100962 CVE-2026-19499 affecting package glibc 2.38-21

Calling strfmon and strfmonl 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 strfmonl with right-justified width padding...

CVE-2026-19499

CVE-2026-19499 is a buffer overflow in the GNU C Library (glibc) versions 2.38 to 2.44 , affecting the strfmon and strfmon_l functions. The root cause is an incorrect length used for an internal memmove operation when a conversion uses right-justified width padding , causing a write past the end ...

CVE-2026-19499 Buffer overflow in strfmon and strfmon_l right-justification padding

Calling strfmon and strfmonl 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 strfmonl with right-justified width padding...

Astra Linux – Vulnerability in glibc

A vulnerable environment variable in the Untrusted LDLIBRARYPATH setting in the GNU C Library, versions 2.27 to 2.38, allows attackers to control the loading of dynamically shared libraries in statically compiled setuid binaries that call dlopen including internal dlopen calls after setlocale or...

Astra Linux – Vulnerability in Redis

A heap overflow issue was discovered in Redis versions prior to 5.0.10, before 6.0.9, and before 6.2.0, when using a heap allocator other than jemalloc or glibc’s malloc function. This issue could lead to out-of-bound writing or the crash of the process. Essentially, this flaw does not affect the...

Astra Linux – Vulnerability in glibc

A use-after-free vulnerability introduced in the glibc upstream version 2.14 was identified in the way the tilde expansion was performed. Directory paths that contained a tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a special...

Astra Linux – Vulnerability in glibc

A flaw was discovered in glibc. A “off-by-one” buffer overflow and underflow in the getcwd function may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and the size passed to getcwd in a setuid program could exploit this flaw t...
