Synopsis
========
Multiple vulnerabilities in Comix may lead to execution of arbitrary
commands and a Denial of Service.
Background
==========
Comix is a GTK comic book viewer.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/comix < 3.6.4-r1 >= 3.6.4-r1
Description
===========
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
======
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.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Comix users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/comix-3.6.4-r1"
