Synopsis |
16 |
======== |
17 |
|
18 |

19 |
execution of arbitrary code or to a Denial of Service. |
20 |
|
21 |
Background |
22 |

Description |
36 |
=========== |
37 |
|
38 |
Brandon Perry discovered that Gaim is vulnerable to a heap-based buffer |
39 |
overflow when handling away messages (CAN-2005-2103). Furthermore, |
40 |
Daniel Atallah discovered a vulnerability in the handling of file |
41 |
transfers (CAN-2005-2102). |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could create a specially crafted away message which, |
47 |
when viewed by the target user, could lead to the execution of |
48 |
arbitrary code. Also, an attacker could send a file with a non-UTF8 |
49 |
filename to a user, which would result in a Denial of Service. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All Gaim users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=net-im/gaim-1.5.0" |
