Descriptions

Integer overflow in the xfs_acl_from_disk function in fs/xfs/xfs_acl.c in the Linux kernel before 3.1.9 allows local users to cause a denial of service (panic) via a filesystem with a malformed ACL, leading to a heap-based buffer overflow.

Desbordamiento de entero en la función xfs_acl_from_disk en fs/xfs/xfs_acl.c en el núcleo de Linux anterior a v3.1.9 que permite a usuarios locales causar una denegación de servicio (panic) a través del sistema de ficheros con una lista ACL mal construida, dando lugar a un desbordamiento de búfer basado en heap.
