CWE-264  (opens in a new tab)

How to fix?

Upgrade Echo:latest clamav to version 0.97.5+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream clamav package and not the clamav package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The Microsoft CHM file parser in ClamAV 0.96.4 and Sophos Anti-Virus 4.61.0 allows remote attackers to bypass malware detection via a crafted reset interval in the LZXC header of a CHM file. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different CHM parser implementations.
