Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple integer overflows have been discovered in ImageMagick allowing |
| 19 |
for the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
ImageMagick is a collection of tools allowing various manipulations on |
| 25 |
image files. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-gfx/imagemagick < 6.3.3 >= 6.3.3 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
iDefense Labs has discovered multiple integer overflows in ImageMagick |
| 39 |
in the functions ReadDCMImage() and ReadXWDImage(), that are used to |
| 40 |
process DCM and XWD files. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An attacker could entice a user to open specially crafted XWD or DCM |
| 46 |
file, resulting in heap-based buffer overflows and possibly the |
| 47 |
execution of arbitrary code with the privileges of the user running |
| 48 |
ImageMagick. Note that this user may be httpd or any other account used |
| 49 |
by applications relying on the ImageMagick tools to automatically |
| 50 |
process images. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All ImageMagick users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.3.3" |
| 64 |
|
