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 new vulnerabilities.
<impact type="normal">
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.
There is no immediate workaround; a software upgrade is required.
All users are recommended to upgrade GAIM to 0.75-r7.
