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.
