Description

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.

A flaw was found in the way the Pidgin MSN protocol plug-in processed text that was not encoded in UTF-8. A remote attacker could use this flaw to crash Pidgin by sending a specially-crafted MSN message. (CVE-2012-1178)

An input validation flaw was found in the way the Pidgin MSN protocol plug-in handled MSN notification messages. A malicious server or a remote attacker could use this flaw to crash Pidgin by sending a specially-crafted MSN notification message. (CVE-2012-2318)

A buffer overflow flaw was found in the Pidgin MXit protocol plug-in. A remote attacker could use this flaw to crash Pidgin by sending a MXit message containing specially-crafted emoticon tags. (CVE-2012-3374)

Red Hat would like to thank the Pidgin project for reporting the CVE-2012-3374 issue. Upstream acknowledges Ulf Harnhammar as the original reporter of CVE-2012-3374.
