Mozilla Firefox is the popular next-generation browser from the
Mozilla project.
The following vulnerabilities were found and fixed in Mozilla
Firefox:
- Mark Dowd from ISS X-Force reported an
exploitable heap overrun in the GIF processing of obsolete Netscape
extension 2 (CAN-2005-0399)
- Kohei Yoshino discovered that a
page bookmarked as a sidebar could bypass privileges control
(CAN-2005-0402)
- Michael Krax reported a new way to bypass XUL
security restrictions through drag-and-drop of items like scrollbars
(CAN-2005-0401)
- The GIF heap overflow could be triggered by a malicious GIF
image that would end up executing arbitrary code with the rights of the
user running Firefox
- By tricking the user into bookmarking a
malicious page as a Sidebar, a remote attacker could potentially
execute arbitrary code with the rights of the user running the
browser
- By setting up a malicious website and convincing users
to obey very specific drag-and-drop instructions, attackers may
leverage drag-and-drop features to bypass XUL security restrictions,
which could be used as a stepping stone to exploit other
vulnerabilities
There is no known workaround at this time.
All Mozilla Firefox users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.2"
All Mozilla Firefox binary users should upgrade to the latest
