Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in ImageMagick, possibly |
| 19 |
resulting in arbitrary code execution or a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
ImageMagick is a collection of tools and libraries for manipulating |
| 25 |
various image formats. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-gfx/imagemagick < 6.3.5.10 >= 6.3.5.10 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
regenrecht reported multiple infinite loops in functions ReadDCMImage() |
| 39 |
and ReadXCFImage() (CVE-2007-4985), multiple integer overflows when |
| 40 |
handling certain types of images (CVE-2007-4986, CVE-2007-4988), and an |
| 41 |
off-by-one error in the ReadBlobString() function (CVE-2007-4987). |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could entice a user to open a specially crafted |
| 47 |
image, possibly resulting in the remote execution of arbitrary code |
| 48 |
with the privileges of the user running the application, or an |
| 49 |
excessive CPU consumption. Note that applications relying on |
| 50 |
ImageMagick to process images can also trigger the vulnerability. |
| 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-6.3.5.10" |
| 64 |
|
| 65 |
