Synopsis
=======

Gaim contains multiple vulnerabilities that can lead to a Denial of Service.

Background
=========

Gaim is a full featured instant messaging client which handles a variety of instant messaging protocols.

Affected packages
================

-------------------------------------------------------------------

Description
==========

Multiple vulnerabilities have been addressed in the latest release of Gaim:

* A buffer overread in the gaim_markup_strip_html() function, which is used when logging conversations (CAN-2005-0965).

* Markup tags are improperly escaped using Gaim's IRC plugin (CAN-2005-0966).

* Sending a specially crafted file transfer request to a Gaim Jabber user can trigger a crash (CAN-2005-0967).

Impact

An attacker could possibly cause a Denial of Service by exploiting any of these vulnerabilities.

Workaround

There is no known workaround at this time.
