Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

errors to the service instead of the client when enforcing
permissions. A local user can use this issue to possibly deny access
to the service. (CVE-2014-3477)

file descriptors. A local attacker could use this issue to cause
