Subject: [USN-106-1] Gaim vulnerabilities

===========================================================
Ubuntu Security Notice USN-106-1	     April 05, 2005
gaim vulnerabilities
CAN-2005-0965, CAN-2005-0966
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

gaim

The problem can be corrected by upgrading the affected package to
version 1:1.0.0-1ubuntu1.3. You have to restart gaim after a standard
system upgrade to effect the necessary changes. 

Details follow:

Jean-Yves Lefort discovered a buffer overflow in the
gaim_markup_strip_html() function. This caused Gaim to crash when
receiving certain malformed HTML messages. (CAN-2005-0965)

Jean-Yves Lefort also noticed that many functions that handle IRC
commands do not escape received HTML metacharacters; this allowed
remote attackers to cause a Denial of Service by injecting arbitrary
HTML code into the conversation window, popping up arbitrarily many
empty dialog boxes, or even causing Gaim to crash. (CAN-2005-0966)
