Synopsis |
17 |
======== |
18 |
|
19 |
Multiple integer overflow vulnerabilities in the AMD64 x86 emulation |
20 |
GTK+ libraries may result in the execution of arbitrary code in |
21 |
applications using Cairo. |
22 |
|
23 |
Background |
24 |
========== |
25 |
|
26 |
Cairo is a 2D vector graphics library with cross-device output support. |
27 |
The AMD64 x86 emulation GTK+ library packages Cairo libraries for 32bit |
28 |
x86 emulation on AMD64. |
29 |
|
30 |
Affected packages |
31 |
================= |
32 |
|

------------------------------------------------------------------- |
34 |
Package / Vulnerable / Unaffected |
35 |
------------------------------------------------------------------- |
36 |

# Package 1 only applies to AMD64 users. |

Description |
41 |
=========== |
42 |
|
43 |
The Cairo versions used by the AMD64 x86 emulation GTK+ libraries were |
44 |
vulnerable to integer overflow vulnerabilities (GLSA 200712-04). |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
A remote attacker could entice a user to view or process a specially |
50 |
crafted PNG image file in an application linked against Cairo, possibly |
51 |
leading to the execution of arbitrary code with the privileges of the |
52 |
user running the application. |
53 |
|
54 |
Workaround |
55 |
========== |
56 |
|
57 |
There is no known workaround at this time. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All AMD64 x86 emulation GTK+ library users should upgrade to the latest |
63 |
version: |
64 |
|
65 |
# emerge --sync |
66 |
# emerge -a -1 -v ">=app-emulation/emul-linux-x86-gtklibs-20071214" |
67 |
