Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

A flaw was found in the way the X.Org server handled lock files. A
local user with access to the system console could use this flaw to
determine the existence of a file in a directory not accessible to the
user, via a symbolic link attack. (CVE-2011-4028)

A race condition was found in the way the X.Org server managed
temporary lock files. A local attacker could use this flaw to perform
a symbolic link attack, allowing them to make an arbitrary file world
readable, leading to the disclosure of sensitive information.
