Descriptions
A vulnerability was found in Linux kernel's, versions up to 3.10, implementation of overlayfs. An attacker with local access can create a denial of service situation via NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c. This can allow attackers with ability to create directories on overlayfs to crash the kernel creating a denial of service (DOS).
Se encontró una vulnerabilidad en la implementación de overlayfs, versiones hasta 3.10, del kernel de Linux. Un atacante con acceso local puede crear una situación de denegación de servicio por medio de una desreferencia del puntero NULL en la función ovl_posix_acl_create en el archivo fs/overlayfs/dir.c. Esto puede permitir a los atacantes con la capacidad para crear directorios en overlayfs, bloquear el kernel creando una denegación de servicio (DOS).
