CVE-2005-3500 The tnef_attachment function in Clam AntiVirus before 0.87.1 allows remote attackers to cause a denial of service, through an infinate loop and memory exhaustion, by crafting a CAB file with a value that causes ClamAV to repeatedly scan the same block CVE-2005-3501 The cabd_find function in of the libmspack library in Clam AntiVirus before 0.87.1 allows remote attackers to cause a denial of service via a crafted CAB file that causes cabd_find to be called with a zero length. CVE-2005-3303 The FSB unpacker in Clam AntiVirus 0.80 through 0.87 allows remote attackers to cause memory corruption and execute arbitrary code via a crafted FSG 1.33 file. For the testing distribution (etch) this is fixed in version 0.87.1-0etch.1 For the unstable distribution (sid) this is fixed in version 0.87.1 This upgrade is recommended if you use clamav. The Debian testing security team does not track security issues for the stable (sarge) and oldstable (woody) distributions. If stable is vulnerable, the Debian security team will make an announcement once a fix is ready.
