Descriptions

A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.

Se ha encontrado un fallo de desbordamiento de búfer en la región heap de la memoria en la forma en que la función legacy_parse_param de la funcionalidad Filesystem Context del kernel de Linux verifica la longitud de los parámetros suministrados. Un usuario local no privilegiado (en caso de tener habilitados los espacios de nombres de usuario no privilegiado, de lo contrario necesita el privilegio CAP_SYS_ADMIN) capaz de abrir un sistema de archivos que no soporta la API Filesystem Context (y por lo tanto los fallbacks a la administración de legado) podría usar este fallo para escalar sus privilegios en el sistema

Linux kernel contains a heap-based buffer overflow vulnerability in the legacy_parse_param function in the Filesystem Context functionality. This allows an attacker to open a filesystem that does not support the Filesystem Context API and ultimately escalate privileges.
