ClamAV < 0.93.1 memcpy() .chm File Handling DoS (deprecated)



The remote host is vulnerable to a Denial of Service (DoS) attack.


The remote host is running ClamAV client.

This version of ClamAV is vulnerable to a flaw within the 'libclamav/chmunpack.c' file. Specifically, when handling malformed '.chm' files, the application fails to adequately parse the file. An attacker sending a malformed .chm file to a server running ClamAV would be able to crash the service.


Upgrade to version 0.93.1 or higher.
