Descriptions

The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.

La implementación Btrfs en el kernel de Linux anterior a 3.19 no asegura que el estado xattr visible sea consistente con un remplazo solicitado, lo que permite a usuarios locales evadir las configuraciones ACL y ganar privilegios a través de las operaciones del sistema de ficheros estándares (1) durante una ventana de tiempo de remplazo de xattr, relacionado con una condición de carrera o (2) después de intento de remplazo de xattr que falla porque la fecha no encaja.
