Synopsis |
16 |
======== |
17 |
|
18 |
An integer overflow vulnerability in wxGTK might enable remote |
19 |
attackers to cause the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
wxGTK is the GTK+ version of wxWidgets, a cross-platform C++ GUI |
25 |
toolkit. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 x11-libs/wxGTK < 2.8.10.1-r1 *>= 2.6.4.0-r5 |
34 |
>= 2.8.10.1-r1 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
wxGTK is prone to an integer overflow error in the wxImage::Create() |
40 |
function in src/common/image.cpp, possibly leading to a heap-based |
41 |
buffer overflow. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker might entice a user to open a specially crafted JPEG |
47 |
file using a program that uses wxGTK, possibly resulting in the remote |
48 |
execution of arbitrary code with the privileges of the user running the |
49 |
application. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All wxGTK 2.6 users should upgrade to an updated version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=x11-libs/wxGTK-2.6.4.0-r5" |
63 |
|
64 |
All wxGTK 2.8 users should upgrade to an updated version: |
65 |
|
66 |
# emerge --sync |
67 |
# emerge --ask --oneshot --verbose ">=x11-libs/wxGTK-2.8.10.1-r1" |
