Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple vulnerabilities in Comix may lead to execution of arbitrary |
| 22 |
commands and a Denial of Service. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
Comix is a GTK comic book viewer. |
| 28 |
|
| 29 |
Affected packages |
| 30 |
================= |
| 31 |
|
| 32 |
------------------------------------------------------------------- |
| 33 |
Package / Vulnerable / Unaffected |
| 34 |
------------------------------------------------------------------- |
| 35 |
1 media-gfx/comix < 3.6.4-r1 >= 3.6.4-r1 |
| 36 |
|
| 37 |
Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Comix does not properly sanitize filenames containing shell |
| 41 |
metacharacters when they are passed to the rar, unrar, or jpegtran |
| 42 |
programs (CVE-2008-1568). Comix also creates directories with |
| 43 |
predictable names (CVE-2008-1796). |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
A remote attacker could exploit the first vulnerability by enticing a |
| 49 |
user to use Comix to open a file with a specially crafted filename, |
| 50 |
resulting in the execution of arbitrary commands. The second |
| 51 |
vulnerability could be exploited by a local attacker to cause a Denial |
| 52 |
of Service by creating a file or directory with the same filename as |
| 53 |
the predictable filename used by Comix. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All Comix users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=media-gfx/comix-3.6.4-r1" |
| 67 |
