GLSA-200712-20 : ClamAV: Multiple vulnerabilities

critical Nessus Plugin ID 29817


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


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.


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