A vulnerability was discovered in ClamAV and corrected with the 0.93.1 release :

libclamav/petite.c in ClamAV before 0.93.1 allows remote attackers to cause a denial of service via a crafted Petite file that triggers an out-of-bounds read. (CVE-2008-2713)

Other bugs have also been corrected in 0.93.1 which is being provided with this update.

The remote host is affected by the vulnerability described in GLSA-200808-07 (ClamAV: Multiple Denials of Service)

    Damian Put has discovered an out-of-bounds memory access while     processing Petite files (CVE-2008-2713, CVE-2008-3215). Also, please     note that the 0.93 ClamAV branch fixes the first of the two attack     vectors of CVE-2007-6595 concerning an insecure creation of temporary     files vulnerability. The sigtool attack vector seems still unfixed.
  Impact :

    A remote attacker could entice a user or automated system to scan a     specially crafted Petite file, possibly resulting in a Denial of     Service (daemon crash). Also, the insecure creation of temporary files     vulnerability can be triggered by a local user to perform a symlink     attack.
  Workaround :

    There is no known workaround at this time.

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.

Backport upstream fix for CVE-2008-2713 (0.93.1) and fix for incomplete fix of CVE-2008-2713 (0.93.2).
