Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been found in Gnash which could result in |
19 |
execution of arbitrary code, Denial of Service, or information |
20 |
disclosure. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |

Description |
36 |
=========== |
37 |
|
38 |
Multiple vulnerabilities have been found in Gnash: |
39 |
|
40 |
* The "nsPluginInstance::setupCookies()" function in plugin.cpp creates |
41 |
world-readable cookies with predictable file names (CVE-2011-4328). |
42 |
* The "GnashImage::size()" function in GnashImage.h contains an integer |
43 |
overflow error which could cause a heap-based buffer overflow |
44 |
(CVE-2012-1175). |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
A remote attacker could entice a user to open a specially crafted SWF |
50 |
file, possibly resulting in execution of arbitrary code or a Denial of |
51 |
Service condition. Furthermore, a local attacker may be able to obtain |
52 |
sensitive information. |
53 |
|
54 |
Workaround |
55 |
========== |
56 |
|
57 |
There is no known workaround at this time. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All Gnash users should upgrade to the latest version: |
63 |
|
64 |
# emerge --sync |
65 |
# emerge --ask --oneshot --verbose ">=www-plugins/gnash-0.8.10-r2" |
66 |
