Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a |
| 44 |
Denial of Service vulnerability in the XWD decoder of ImageMagick and |
| 45 |
GraphicsMagick when setting a color mask to zero. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A remote attacker could submit a specially crafted image to a user or |
| 51 |
an automated system making use of an affected utility, resulting in a |
| 52 |
Denial of Service by consumption of CPU time. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All ImageMagick users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.2.2.3" |
| 66 |
|
| 67 |
All GraphicsMagick users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.6-r1" |
