Synopsis :

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

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.
