Description

Several denial-of-service vulnerabilities have been discovered in the ClamAV anti-virus toolkit :

Insufficient checking for out-of-memory conditions results in NULL pointer dereferences (CVE-2008-3912 ).

Incorrect error handling logic leads to memory leaks (CVE-2008-3913 ) and file descriptor leaks (CVE-2008-3914 ).
