A fuzzing test showed weakness in the chm parser of clamav, which can
possibly be exploited.
The clamav team has disabled the chm module in older versions though freshclam updates and has released 0.94 with a fixed parser.
The clamav team has not mentioned this issue in the release notes of 0.94, which is very bad security behaviour.
