Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
libXpm contains several vulnerabilities that could lead to a Denial of |
| 19 |
Service and arbitrary code execution. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
libXpm is a pixmap manipulation library for the X Window System, |
| 25 |
included in both X.Org and XFree86. |
| 26 |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Several issues were discovered in libXpm, including integer overflows, |
| 44 |
out-of-bounds memory accesses, insecure path traversal and an endless |
| 45 |
loop. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
An attacker could craft a malicious pixmap file and entice a user to |
| 51 |
use it with an application linked against libXpm. This could lead to |
| 52 |
Denial of Service or arbitrary code execution. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All X.Org users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.7.0-r3" |
| 66 |
|
| 67 |
All XFree86 users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=x11-base/xfree-x11-4.3.0-r8" |
| 71 |
