The remote Red Hat host is missing one or more security updates.
Updated firefox packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.
This update has been rated as having critical security impact by the
Red Hat Security Response Team.
Mozilla Firefox is an open source Web browser. XULRunner provides the
XUL Runtime environment for Mozilla Firefox.
Several flaws were found in the processing of malformed web content. A
web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user
running Firefox. (CVE-2009-3979, CVE-2009-3981, CVE-2009-3986)
A flaw was found in the Firefox NT Lan Manager (NTLM) authentication
protocol implementation. If an attacker could trick a local user that
has NTLM credentials into visiting a specially crafted web page, they
could send arbitrary requests, authenticated with the user's NTLM
credentials, to other applications on the user's system.
A flaw was found in the way Firefox displayed the SSL location bar
indicator. An attacker could create an unencrypted web page that
appears to be encrypted, possibly tricking the user into believing
they are visiting a secure page. (CVE-2009-3984)
A flaw was found in the way Firefox displayed blank pages after a user
navigates to an invalid address. If a user visits an
attacker-controlled web page that results in a blank page, the
attacker could inject content into that blank page, possibly tricking
the user into believing they are viewing a legitimate page.
For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 3.0.16. You can find a link to the
Mozilla advisories in the References section of this errata.
All Firefox users should upgrade to these updated packages, which
contain Firefox version 3.0.16, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
