Descriptions

namei in FreeBSD 9.1 through 10.1-RC2 allows remote attackers to cause a denial of service (memory exhaustion) via vectors that trigger a sandboxed process to look up a large number of nonexistent path names.

namei en FreeBSD 9.1 hasta 10.1-RC2 permite a atacantes remotos causar una denegación de servicio (agotamiento de memoria) a través de vectores que provocan que un proceso de sandbox busque un número grande de nombres de rutas no existentes.

The namei facility will leak a small amount of kernel memory every time a sandboxed process looks up a nonexistent path name. A remote attacker that can cause a sandboxed process (for instance, a web server) to look up a large number of nonexistent path names can cause memory exhaustion.
