Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously. Info/Query is an Extensible Messaging and Presence Protocol specific request-response mechanism. A NULL pointer dereference flaw was found in the way the Pidgin XMPP protocol plug-in processes IQ error responses when trying to fetch a custom smiley. A remote client could send a specially-crafted IQ error response that would crash Pidgin. A NULL pointer dereference flaw was found in the way the Pidgin IRC protocol plug-in handles IRC topics. A malicious IRC server could send a specially-crafted IRC TOPIC message, which once received by Pidgin, would lead to a denial of service . It was discovered that, when connecting to certain, very old Jabber servers via XMPP, Pidgin may ignore the "Require SSL/TLS" setting. In these situations, a non-encrypted connection is established rather than the connection failing, causing the user to believe they are using an encrypted connection when they are not, leading to sensitive information disclosure . A NULL pointer dereference flaw was found in the way the Pidgin MSN protocol plug-in handles improper MSNSLP invitations. A remote attacker could send a specially-crafted MSNSLP invitation request, which once accepted by a valid Pidgin user, would lead to a denial of service . These packages upgrade Pidgin to version 2.6.2. Pidgin must be restarted for this update to take effect.
