Descriptions

The load_flat_shared_library function in fs/binfmt_flat.c in the flat subsystem in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by executing a shared flat binary, which triggers an access of an "uninitialized cred pointer."

La función load_flat_shared_library en el archivo fs/binfmt_flat.c en el subsistema flat en el kernel de Linux anterior a versión 2.6.31-rc6, permite a los usuarios locales causar una denegación de servicio (desreferencia de un puntero NULL y bloqueo del sistema) o posiblemente tener otro impacto no especificado mediante la ejecución de un binario flat compartido, que activa el acceso de un "uninitialized cred pointer."

The Linux 2.6 kernel has been updated to mitigate multiple vulnerabilities related to denial of service, arbitrary code execution, stack memory disclosure, restriction bypass, and more.
