Descriptions

The d_delete function in fs/ecryptfs/inode.c in eCryptfs in the Linux kernel 2.6.31 allows local users to cause a denial of service (kernel OOPS) and possibly execute arbitrary code via unspecified vectors that cause a "negative dentry" and trigger a NULL pointer dereference, as demonstrated via a Mutt temporary directory in an eCryptfs mount.

La función d_delete function en fs/ecryptfs/inode.c en eCryptfs en el kernel de Linux v2.6.31 permite a usuarios locales causar una denegación de servicio (kernel OOPS) y probablemente ejecutar código de su elección a través de vectores no especificados que causa una "entrada negativa" y ejecuta una deferencia a puntero NULL, como fue demostrado a través del directorio temporal Mutt en eCryptifs.
