Updated mozilla packages that fix various bugs are now available.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Mozilla is an open source Web browser, advanced email and newsgroup client,
IRC chat client, and HTML editor.

A buffer overflow bug was found in the way Mozilla processes GIF images. It
is possible for an attacker to create a specially crafted GIF image, which
when viewed by a victim will execute arbitrary code as the victim. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-0399 to this issue.

A bug was found in the way Mozilla displays dialog windows. It is possible
that a malicious web page which is being displayed in a background tab
could present the user with a dialog window appearing to come from the
active page. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-1380 to this issue.

A bug was found in the way Mozilla allowed plug-ins to load privileged
content into a frame. It is possible that a malicious webpage could trick a
user into clicking in certain places to modify configuration settings or
execute arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0232 to this issue.

A bug was found in the way Mozilla Mail handles cookies when loading
content over HTTP regardless of the user's preference. It is possible that
a particular user could be tracked through the use of malicious mail
messages which load content over HTTP. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0149 to
this issue.

A bug was found in the way Mozilla responds to proxy auth requests. It is
possible for a malicious webserver to steal credentials from a victims
browser by issuing a 407 proxy authentication request. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0147 to this issue.

A bug was found in the way Mozilla handles certain start tags followed by a
NULL character. A malicious web page could cause Mozilla to crash when
viewed by a victim. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-1613 to this issue.

A bug was found in the way Mozilla sets file permissions when installing
XPI packages. It is possible for an XPI package to install some files
world readable or writable, allowing a malicious local user to steal
information or execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0906 to
this issue.

A bug was found in the way Mozilla loads links in a new tab which are
middle clicked. A malicious web page could read local files or modify
privileged chrom settings. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0141 to this issue.

A bug was found in the way Mozilla displays the secure site icon. A
malicious web page can use a view-source URL targetted at a secure page,
while loading an insecure page, yet the secure site icon shows the previous
secure state. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0144 to this issue.
