Descriptions

The XFS implementation in the Linux kernel before 3.15 improperly uses an old size value during remote attribute replacement, which allows local users to cause a denial of service (transaction overrun and data corruption) or possibly gain privileges by leveraging XFS filesystem access.

La implementación XFS en el Kernel de Linux anterior a 3.15 utiliza inadecuadamente un valor de tamaño antiguo durante el reemplazo del atributo remoto, lo que permite a usuarios locales causar una denegación de servicio (transacción de saturación y corrupción de datos) o la posibilidad de obtener privilegios aprovechando el acceso al sistema de archivos XFS.

A flaw was found in the way the Linux kernel's XFS file system handled replacing of remote attributes under certain conditions. A local user with access to XFS file system mount could potentially use this flaw to escalate their privileges on the system.
