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.
