RHSA-2008:0549 - Security Advisory

Topic

An updated firefox package that fixes several security issues is now
available for Red Hat Enterprise Linux 4.

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

Description

Mozilla Firefox is an open source Web browser.

Multiple flaws were found in the processing of malformed JavaScript
content. A web page containing such malicious content could cause Firefox
to crash or, potentially, execute arbitrary code as the user running
Firefox. (CVE-2008-2801, CVE-2008-2802, CVE-2008-2803)

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 as the user running Firefox.
(CVE-2008-2798, CVE-2008-2799, CVE-2008-2811)

Several flaws were found in the way malformed web content was displayed. A
web page containing specially-crafted content could potentially trick a
Firefox user into surrendering sensitive information. (CVE-2008-2800)

Two local file disclosure flaws were found in Firefox. A web page
containing malicious content could cause Firefox to reveal the contents of
a local file to a remote attacker. (CVE-2008-2805, CVE-2008-2810)

A flaw was found in the way a malformed .properties file was processed by
Firefox. A malicious extension could read uninitialized memory, possibly
leaking sensitive data to the extension. (CVE-2008-2807)

A flaw was found in the way Firefox escaped a listing of local file names.
If a user could be tricked into listing a local directory containing
malicious file names, arbitrary JavaScript could be run with the
permissions of the user running Firefox. (CVE-2008-2808)

A flaw was found in the way Firefox displayed information about self-signed
certificates. It was possible for a self-signed certificate to contain
multiple alternate name entries, which were not all displayed to the user,
allowing them to mistakenly extend trust to an unknown site.
(CVE-2008-2809)

All Mozilla Firefox users should upgrade to this updated package, which
contains backported patches that correct these issues.
