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. 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 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. ~ $> emerge sync ~ $> emerge -pv ">=net-im/gaim-0.75-r7" ~ $> emerge ">=net-im/gaim-0.75-r7" References ========== ~ [ 1 ] : http://www.securityfocus.com/archive/1/351235 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@...too.org or alternatively, you may file a bug at http://bugs.gentoo.org. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFAFrwkMMXbAy2b2EIRAgXNAKDv5xVitt263W3Zuhbr0XbYFFn60ACdGdKO 7ltFFxnxeXHJbOmb3BkQLOM= =shTi -----END PGP SIGNATURE----- _______________________________________________ Full-Disclosure - We believe in it.
