Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
ImageMagick contains an error in boundary checks when handling EXIF |
| 19 |
information, which could lead to arbitrary code execution. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
ImageMagick is a collection of tools to read, write and manipulate |
| 25 |
images in many formats. |
| 26 |
|
| 27 |

| 31 |
Package / Vulnerable / Unaffected |
| 32 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
ImageMagick fails to do proper bounds checking when handling image |
| 39 |
files with EXIF information. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker could use an image file with specially-crafted EXIF |
| 45 |
information to cause arbitrary code execution with the permissions of |
| 46 |
the user running ImageMagick. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All ImageMagick users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.1.3.2" |
| 60 |
|
