Gentoo Linux Security Advisory GLSA 200804-29

                                        http://security.gentoo.org/

Severity: Normal
Title: Comix: Multiple vulnerabilities
Date: April 25, 2008
Bugs: #215694
ID: 200804-29

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 &quot;&gt;=media-gfx/comix-3.6.4-r1&quot;
