Gentoo: GLSA-200401-04: GAIM 0.75 Remote overflows
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200401-04 ~ https://security.gentoo.org/
~ Severity: Normal ~ Title: GAIM 0.75 Remote overflows ~ Date: January 27, 2004 ~ Bugs: #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.
========== 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 vulnerabilities [ 1 ].
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.
