The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201110-19
(X.Org X Server: Multiple vulnerabilities)
vladz reported the following vulnerabilities in the X.Org X server:
The X.Org X server follows symbolic links when trying to access the
lock file for a X display, showing a predictable behavior depending on
the file type of the link target (CVE-2011-4028).
The X.Org X server lock file mechanism allows for a race condition to
cause the X server to modify the file permissions of an arbitrary file
to 0444 (CVE-2011-4029).
A local attacker could exploit these vulnerabilities to disclose
information by making arbitrary files on a system world-readable or gain
information whether a specified file exists on the system and whether it
is a file, directory, or a named pipe.
There is no known workaround at this time.
