Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in Gaim which could allow a |
| 19 |
remote attacker to crash the application, or possibly execute |
| 20 |
arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Gaim is a full featured instant messaging client which handls a variety |
| 26 |
of instant messaging protocols. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 net-im/gaim < 1.0.2 >= 1.0.2 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
A possible buffer overflow exists in the code processing MSN SLP |
| 40 |
messages (CAN-2004-0891). memcpy() was used without validating the size |
| 41 |
of the buffer, and an incorrect buffer was used as destination under |
| 42 |
certain circumstances. Additionally, memory allocation problems were |
| 43 |
found in the processing of MSN SLP messages and the receiving of files. |
| 44 |
These issues could lead Gaim to try to allocate more memory than |
| 45 |
available, resulting in the crash of the application. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A remote attacker could crash Gaim and possibly execute arbitrary code |
| 51 |
by exploiting the buffer overflow. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All Gaim users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge sync |
| 64 |
|
| 65 |
# emerge -pv ">=net-im/gaim-1.0.2" |
| 66 |
# emerge ">=net-im/gaim-1.0.2" |
| 67 |
|
| 68 |
