Gentoo Linux Security Advisory
Title: GAIM 0.75 Remote overflows (GLSA 200401-04)
Severity: normal
Exploitable: man-in-the-middle
Date: January 26, 2004
Bug(s): #39470
ID: 200401-04
Synopsis
Various overflows in the handling of AIM DirectIM packets was revealed in
GAIM that could lead to a remote compromise of the IM client.
Background
Gaim is a multi-platform and multi-protocol instant messaging
client. It is compatible with AIM , ICQ, MSN Messenger, Yahoo,
IRC, Jabber, Gadu-Gadu, and the Zephyr networks.
Affected Packages
Package: net-im/gaim
Vulnerable: < 0.75-r7
Unaffected: >= 0.75-r7
Architectures: All supported architectures
Description
Yahoo changed the authentication methods to their IM servers,
rendering GAIM useless. The GAIM team released a rushed release
solving this issue, however, at the same time a code audit
revealed 12 new vulnerabilities.
Impact
Due to the nature of instant messaging many of these bugs require
man-in-the-middle attacks between the client and the server. But
the underlying protocols are easy to implement and attacking
ordinary TCP sessions is a fairly simple task. As a result, all
users are advised to upgrade their GAIM installation.
-
Users of GAIM 0.74 or below are affected by 7 of the
vulnerabilities and are encouraged to upgrade.
-
Users of GAIM 0.75 are affected by 11 of the vulnerabilities
and are encouraged to upgrade to the patched version of GAIM
offered by Gentoo.
-
Users of GAIM 0.75-r6 are only affected by
4 of the vulnerabilities, but are still urged to upgrade to
maintain security.
Workaround
There is no immediate workaround; a software upgrade is required.
Resolution
All users are recommended to upgrade GAIM to 0.75-r7.
Code: | $> emerge sync
$> emerge -pv ">=net-im/gaim-0.75-r7"
$> emerge ">=net-im/gaim-0.75-r7" |
