OVERVIEW

possible DoS attack by a special crafted TAR archive file

DETAIL

The AMaViS shell script version (AMaViS 0.1.x / 0.2.x) uses securetar.
securetar removes the pathes of files in a tar archive and makes each
file name a unique name. Links, character devices, block devices and named
pipes will be removed from the archive.
A special-crafted TAR file may hung securetar forever, using up to
100% CPU time.

SOLUTION

It is recommended that all Gentoo Linux users who are running
net-mail/amavis-0.2.1-r2 and earlier update their systems
as follows:

emerge rsync
emerge amavis
emerge clean
