Gaim: Denial of Service issues

Background

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

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.

Resolution

All Gaim users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-im/gaim-1.2.1"
