Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The PNG image decoding routines in the GD library contain an integer |
| 19 |
overflow that may allow execution of arbitrary code with the rights of |
| 20 |
the program decoding a malicious PNG image. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
The GD graphics library is an open source library which allows |
| 26 |
programmers to easily generate PNG, JPEG, GIF and WBMP images from many |
| 27 |
different programming languages. |
| 28 |
|
| 29 |
Affected packages |
| 30 |
================= |
| 31 |
|
| 32 |
------------------------------------------------------------------- |
| 33 |
Package / Vulnerable / Unaffected |
| 34 |

1 media-libs/gd < 2.0.32 >= 2.0.32 |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
infamous41md found an integer overflow in the memory allocation |
| 41 |
procedure of the GD routine that handles loading PNG image files. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could entice a user to load a carefully crafted PNG |
| 47 |
image file in a GD-powered application, or send a PNG image to a web |
| 48 |
application which uses GD PNG decoding functions. This could |
| 49 |
potentially lead to execution of arbitrary code with the rights of the |
| 50 |
program loading the image. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All GD users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.32" |
| 64 |
