GLSA-200507-28 : AMD64 x86 emulation base libraries: Buffer overflow

This script is Copyright (C) 2005-2014 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-200507-28
(AMD64 x86 emulation base libraries: Buffer overflow)

Earlier versions of emul-linux-x86-baselibs contain a vulnerable
version of zlib, which may lead to a buffer overflow.

Impact :

By creating a specially crafted compressed data stream, attackers can
overwrite data structures for applications that use the x86 emulation
base libraries for AMD64, resulting in a Denial of Service and
potentially arbitrary code execution.

Workaround :

There is no known workaround at this time.

Solution :

All AMD64 x86 emulation base libraries users should upgrade to the
latest version:
# emerge --sync
# emerge --ask --oneshot --verbose app-emulation/emul-linux-x86-baselibs

Risk factor :

High / CVSS Base Score : 7.5
