FreeBSD : FreeBSD -- memory leak in sandboxed namei lookup (73964eac-6007-11e6-a6c3-14dae9d210b8)

Medium Nessus Plugin ID 92910


The remote FreeBSD host is missing one or more security-related updates.


The namei facility will leak a small amount of kernel memory every time a sandboxed process looks up a nonexistent path name. Impact : 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.


Update the affected packages.
