Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
XLI and Xloadimage contain a vulnerability which could potentially |
| 19 |
result in the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
XLI and Xloadimage are X11 image manipulation utilities. |
| 25 |
|
| 26 |
Affected packages |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
When XLI or Xloadimage process an image, they create a new image object |
| 42 |
to contain the new image, copying the title from the old image to the |
| 43 |
newly created image. Ariel Berkman reported that the 'zoom', 'reduce', |
| 44 |
and 'rotate' functions use a fixed length buffer to contain the new |
| 45 |
title, which could be overwritten by the NIFF or XPM image processors. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A malicious user could craft a malicious XPM or NIFF file and entice a |
| 51 |
user to view it using XLI, or manipulate it using Xloadimage, |
| 52 |
potentially resulting in the execution of arbitrary code with the |
| 53 |
permissions of the user running XLI or Xloadimage. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All XLI users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=media-gfx/xli-1.17.0-r2" |
| 67 |
|
| 68 |
All Xloadimage users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=media-gfx/xloadimage-4.1-r4" |
| 72 |
