Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The GD library is prone to a buffer overflow vulnerability. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
GD is a graphic library for fast image creation. |
| 24 |
|
| 25 |
Affected packages |
| 26 |
================= |
| 27 |
|
| 28 |
------------------------------------------------------------------- |
| 29 |
Package / Vulnerable / Unaffected |
| 30 |
------------------------------------------------------------------- |
| 31 |
1 media-libs/gd < 2.0.35-r1 >= 2.0.35-r1 |
| 32 |
|
| 33 |
Description |
| 34 |
=========== |
| 35 |
|
| 36 |
Tomas Hoger reported that the _gdGetColors() function in gd_gd.c does |
| 37 |
not properly verify the colorsTotal struct member, possibly leading to |
| 38 |
a buffer overflow. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could entice a user to open a specially crafted image |
| 44 |
file with a program using the GD library, possibly resulting in the |
| 45 |
remote execution of arbitrary code with the privileges of the user |
| 46 |
running the application, or a Denial of Service condition. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All GD users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.35-r1" |
| 60 |
|
| 61 |
