Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in GraphicsMagick allows attackers to crash the |
| 19 |
application and potentially execute arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
GraphicsMagick is a collection of tools to read, write and manipulate |
| 25 |
images in many formats. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-gfx/graphicsmagick < 1.1.7 >= 1.1.7 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The SetImageInfo function was found vulnerable to a format string |
| 39 |
mishandling. Daniel Kobras discovered that the handling of "%"-escaped |
| 40 |
sequences in filenames passed to the function is inadequate in |
| 41 |
ImageMagick GLSA 200602-06 and the same vulnerability exists in |
| 42 |
GraphicsMagick. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
By feeding specially crafted file names to GraphicsMagick an attacker |
| 48 |
can crash the program and possibly execute arbitrary code with the |
| 49 |
privileges of the user running GraphicsMagick. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All GraphicsMagick users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.7" |
| 63 |
|
