Descriptions

The __nfs4_get_acl_uncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words in an FATTR4_ACL reply. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-4131.

La función __nfs4_get_acl_uncached de fs/nfs/nfs4proc.c de la implementación NFSv4 del kernel de Linux en versiones anteriores a la 3.3.2 utiliza una variable de longitud incorrecta durante una operación de copia, lo que permite a servidores NFS remotos provocar una denegación de servicio (OOPS) enviando un número excesivo de bitmap words en una respuesta FATTR4_ACL. NOTA: esta vulnerabilida existe debido a una solución incompleta de CVE-2011-4131.
