This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200408-16
(glibc: Information leak with LD_DEBUG)

Silvio Cesare discovered a potential information leak in glibc. It
allows LD_DEBUG on SUID binaries where it should not be allowed. This
has various security implications, which may be used to gain
confidentional information.

Impact :

An attacker can gain the list of symbols a SUID application uses and
their locations and can then use a trojaned library taking precendence
over those symbols to gain information or perform further exploitation.

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of glibc.

Solution :

All glibc users should upgrade to the latest version:
# emerge sync
# emerge -pv your_version
# emerge your_version

Risk factor :

Low / CVSS Base Score : 2.1
