Synopsis |
16 |
======== |
17 |
|
18 |
Gaim contains two vulnerabilities, potentially resulting in the |
19 |
execution of arbitrary code or Denial of Service. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Gaim is a full featured instant messaging client which handles a |
25 |
variety of instant messaging protocols. |
26 |
|
27 |
Affected packages |

Description |
36 |
=========== |
37 |
|
38 |
Stu Tomlinson discovered that Gaim is vulnerable to a remote stack |
39 |
based buffer overflow when receiving messages in certain protocols, |
40 |
like Jabber and SILC, with a very long URL (CAN-2005-1261). Siebe |
41 |
Tolsma discovered that Gaim is also vulnerable to a remote Denial of |
42 |
Service attack when receiving a specially crafted MSN message |
43 |
(CAN-2005-1262). |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker could cause a buffer overflow by sending an instant |
49 |
message with a very long URL, potentially leading to the execution of |
50 |
malicious code. By sending a SLP message with an empty body, a remote |
51 |
attacker could cause a Denial of Service or crash of the Gaim client. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There are no known workarounds at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All Gaim users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=net-im/gaim-1.3.0" |
65 |
