Description

Clam AntiVirus ClamAV before 0.90 does not close open file descriptors under certain conditions, which allows remote attackers to cause a denial of service (file descriptor consumption and failed scans) via CAB archives with a cabinet header record length of zero, which causes a function to return without closing a file descriptor.

Affected products

Cisco ClamAV: before 0.90 — fixed in 0.90
Debian Linux: 3.1

How to fix

Upgrade to a fixed version: Apple Mac Os X Server 10.4.11; Cisco ClamAV 0.90. Check the vendor advisory for mitigations.
