Synopsis |
16 |
======== |
17 |
|
18 |
GraphicsMagick improperly handles PALM and DCM images, potentially |
19 |
resulting in the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
GraphicsMagick is a collection of tools and libraries which support |
25 |
reading, writing, and manipulating images in many major formats. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 media-gfx/graphicsmagick < 1.1.7-r3 >= 1.1.7-r3 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
M. Joonas Pihlaja has reported that a boundary error exists within the |
39 |
ReadDCMImage() function of coders/dcm.c, causing the improper handling |
40 |
of DCM images. Pihlaja also reported that there are several boundary |
41 |
errors in the ReadPALMImage() function of coders/palm.c, similarly |
42 |
causing the improper handling of PALM images. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
An attacker could entice a user to open a specially crafted DCM or PALM |
48 |
image with GraphicsMagick, 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-r3" |
