A remote attacker could provide a RX message with specially-crafted emoticon tags, that when processed by the libPurple's MXit protocol plug-in by an application linked against libPurple could lead to that application crash or, potentially, arbitrary code execution with the privileges of the user running the application.

Previous versions of Pidgin contained a vulnerability, discovered by Ulf Härnhammar, in the MXit component, where parsing incoming messages with inline images led to a buffer overflow. The developers say that this could have been exploited by an attacker to execute arbitrary code on a victim's system by using a specially crafted message. Versions up to and including 2.10.4 are affected. Upgrading to Pidgin 2.10.5 fixes the problem; all users are advised to upgrade. Other bugs, including an issue that caused the application to crash, have also been fixed. http://www.pidgin.im/news/security/index.php?id=64 To manage notifications about this bug go to: https://bugs.launchpad.net/pidgin/+bug/1022012/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
