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"
