GLSA-200712-20 : ClamAV: Multiple vulnerabilities

This script is Copyright (C) 2007-2015 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-200712-20
(ClamAV: Multiple vulnerabilities)

iDefense reported an integer overflow vulnerability in the cli_scanpe()
function when parsing Portable Executable (PE) files packed in the MEW
format, that could be exploited to cause a heap-based buffer overflow
(CVE-2007-6335). Toeroek Edwin reported an off-by-one error when
decompressing MS-ZIP compressed CAB files (CVE-2007-6336). An
unspecified vulnerability related to the bzip2 decompression algorithm
has also been discovered (CVE-2007-6337).

Impact :

A remote attacker could entice a user or automated system to scan a
specially crafted file, possibly leading to the execution of arbitrary
code with the privileges of the user running ClamAV (either a system
user or the 'clamav' user if clamd is compromised).

Workaround :

There is no known workaround at this time.

Solution :

All ClamAV users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-antivirus/clamav-0.91.2-r1'

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 8.7
(CVSS2#E:ND/RL:OF/RC:C)
