(RHSA-2008:0549) Critical: firefox security update

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.
