Comix is a GTK comic book viewer.
Comix does not properly sanitize filenames containing shell
metacharacters when they are passed to the rar, unrar, or jpegtran
programs (CVE-2008-1568). Comix also creates directories with
predictable names (CVE-2008-1796).
<impact type="normal">
A remote attacker could exploit the first vulnerability by enticing a
user to use Comix to open a file with a specially crafted filename,
resulting in the execution of arbitrary commands. The second
vulnerability could be exploited by a local attacker to cause a Denial
of Service by creating a file or directory with the same filename as
the predictable filename used by Comix.
There is no known workaround at this time.
All Comix users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/comix-3.6.4-r1&quot;</code>
