Mozilla is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor.
A denial of service bug was found in the way Mozilla saves history information. If a user visits a web page with a very long title, it is possible Mozilla will crash or take a very long time the next time it is run. (CVE-2005-4134)
Note that the Red Hat Enterprise Linux 3 packages also fix a bug when using XSLT to transform documents. Passing DOM Nodes as parameters to functions expecting an xsl:param could cause Mozilla to throw an exception.
Users of Mozilla are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
