Detail

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.

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"
