CVSS: 9.8EPSS: 1%CPEs: 6EXPL: 1CVE-2022-23218 – glibc: Stack-based buffer overflow in svcunix_create via long pathnames
https://notcve.org/view.php?id=CVE-2022-23218
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') •
