Date Reported:
26 Jul 2008
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 490925.
In Mitre's CVE dictionary: CVE-2008-2713, CVE-2008-3215.
More information:

Damian Put discovered a vulnerability in the ClamAV anti-virus toolkit's parsing of Petite-packed Win32 executables. The weakness leads to an invalid memory access, and could enable an attacker to crash clamav by supplying a maliciously crafted Petite-compressed binary for scanning. In some configurations, such as when clamav is used in combination with mail servers, this could cause a system to fail open, facilitating a follow-on viral attack.

A previous version of this advisory referenced packages that were built incorrectly and omitted the intended correction. This issue was fixed in packages referenced by the -2 revision of the advisory.

The Common Vulnerabilities and Exposures project identifies this weakness as CVE-2008-2713 and CVE-2008-3215.

For the stable distribution (etch), this problem has been fixed in version 0.90.1dfsg-3.1+etch14.

For the unstable distribution (sid), this problem has been fixed in version 0.93.1.dfsg-1.1.

We recommend that you upgrade your clamav packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
