17 Apr 2024 — The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. La función iconv() en las versiones 2.39 y anteriores de la librería GNU C puede desbordar el búfer de salida que se le pasa hasta en 4 bytes al convertir cadenas al juego de caracteres ISO-2022-CN-EXT, lo que puede usarse para bloquear una ap... • https://packetstorm.news/files/id/182289 • CWE-787: Out-of-bounds Write •

18 Sep 2023 — A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.

12 Sep 2023 — A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. Se encontró una falla en glibc. En una situación poco común, la función gaih_inet puede utilizar memoria que se ha liberado, lo que provoca un bloqueo de la aplicación. • https://github.com/tnishiox/cve-2023-4813 • CWE-416: Use After Free •

25 Jun 2023 — end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue.

02 Mar 2022 — A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system.
