Description Agostino Sarubbo gentoo-dev 2017-08-23 08:02:03 UTC
From ${URL} :

The wwunpack function in libclamav/wwunpack.c in ClamAV 0.99.2 allows
remote attackers to cause a denial of service (use-after-free) via a
crafted PE file with WWPack compression.

Upstream patch:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
