Descriptions
Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel before 3.18.2 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename.
Error de superación de límite (off-by-one) en la función ecryptfs_decode_from_filename en fs/ecryptfs/crypto.c en el subsistema eCryptfs en el kernel de Linux anterior a 3.18.2 permite a usuarios locales causar una denegación de servicio (desbordamiento de buffer y caída del sistema) o posiblemente ganar privilegios a través de un nombre de fichero manipulado.
A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
