The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. La función de compatibilidad obsoleta svcunix_create en el módulo sunrpc de la Biblioteca C de GNU (también conocida como glibc) hasta la versión 2.34 copia su argumento de ruta en la pila sin comprobar su longitud, lo que puede resultar en un desbordamiento del búfer, resultando potencialmente en una denegación de servicio o (si una aplicación no está construida con un protector de pila habilitado) la ejecución de código arbitrario A stack based buffer-overflow vulnerability was found in the deprecated compatibility function svcunix_create() in the sunrpc's svc_unix.c module of the GNU C Library (aka glibc) through 2.34. This vulnerability copies its path argument onto the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) then it will lead to arbitrary code execution. • https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202208-24 https://sourceware.org/bugzilla/show_bug.cgi?id=28768 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23218 https://bugzilla.redhat.com/show_bug.cgi?id=2042013 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

In librt in the GNU C Library (aka glibc) through 2.34, sysdeps/unix/sysv/linux/mq_notify.c mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. NOTE: this vulnerability was introduced as a side effect of the CVE-2021-33574 fix. En librt en la Biblioteca C de GNU (también se conoce como glibc) versiones hasta 2.34, el archivo sysdeps/unix/sysv/linux/mq_notify.c, maneja inapropiadamente determinados datos NOTIFY_REMOVED, conllevando una desreferencia de puntero NULL.

The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations. La función wordexp de la biblioteca GNU C (también se conoce como glibc) versiones hasta 2.33, puede bloquearse o leer memoria arbitraria en la función parse_param (en el archivo posix/wordexp.c) cuando se llama con un patrón diseñado que no es confiable, resultando en una denegación de servicio o divulgación de información. Esto ocurre porque atoi fue usado pero debería haber sido usado strtoul para asegurar cálculos correctos An integer overflow flaw was found in glibc that may result in reading of arbitrary memory when wordexp is used with a specially crafted untrusted regular expression input. • https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202208-24 https://security.netapp.com/advisory/ntap-20210827-0005 https://sourceware.org/bugzilla/show_bug.cgi?id=28011 https://sourceware.org/git/?p=glibc.git%3Ba=commit%3Bh=5adda61f62b77384718b4c0d8336ade8f2b4b35c https://sourceware.org/glibc/wiki/Security%20Exceptions https://access.redhat.com/security/cve/CVE-2021-35942 https://bugzilla.redhat.com/show_bug.cgi?id=1977975 • CWE-190: Integer Overflow or Wraparound •

The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228. La función iconv en la biblioteca GNU C (también se conoce como glibc o libc6) versiones 2.32 y anteriores, cuando se procesa secuencias de entrada de múltiples bytes no validas en codificaciones IBM1364, IBM1371, IBM1388, IBM1390 e IBM1399, presenta un fallo al avanzar el estado de la entrada, lo que podría conllevar a un bucle infinito en las aplicaciones, resultando en una denegación de servicio, una vulnerabilidad diferente de CVE-2016-10228 A flaw was found in glibc. If an attacker provides the iconv function with invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings, it fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service. • https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202107-07 https://security.netapp.com/advisory/ntap-20210401-0006 https://sourceware.org/bugzilla/show_bug.cgi?id=19519#c21 https://sourceware.org/bugzilla/show_bug.cgi?id=26224 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-27618 https://bugzilla.redhat.com/show_bug.cgi? • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
