Description Jan Lieskovsky 2012-05-07 10:04:57 UTC

A denial service flaw was found in the way XMPP protocol plug-in of Pidgin, a Gtk+ based multiprotocol instant messaging client, performed cleanup for certain SOCKS5 connections. A remote attacker, being present on the buddy list of the victim, and able to trick the victim into accepting of a serie of specially-crafted XMPP file transfer requests, could use this flaw to cause pidgin executable crash.

Comment 3 Jan Lieskovsky 2012-05-07 16:08:03 UTC

The duplicate CVE identifier of CVE-2012-2323 has been also assigned to this issue by mistake:
http://www.openwall.com/lists/oss-security/2012/05/07/12

But CVE-2012-2214 one should be used when referencing to this deficiency (CVE-2012-2323 will rejected as duplicate of CVE-2012-2214).
