Description Murray McAllister 2014-11-24 01:01:03 UTC

A heap-based buffer overflow flaw was found in ClamAV when scanning Windows PE files that were crypted with y0da's Crypter. Scanning a malicious PE file could cause ClamAV to crash or, potentially, execute arbitrary code.

Upstream fix:

https://github.com/vrtadmin/clamav-devel/commit/fc3794a54d2affe5770c1f876484a871c783e91e

Which ClamAV release contains a fix? 0.98.5 already? Or 0.98.6?

Ah, http://seclists.org/oss-sec/2014/q4/752 answers it (0.98.5 contains a
