Scientific Linux Security Update : firefox on SL4.x, SL5.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A flaw was found in the way Firefox sanitized HTML content in
extensions. If an extension loaded or rendered malicious content using
the ParanoidFragmentSink class, it could fail to safely display the
content, causing Firefox to execute arbitrary JavaScript with the
privileges of the user running Firefox. (CVE-2010-1585)

A flaw was found in the way Firefox handled dialog boxes. An attacker
could use this flaw to create a malicious web page that would present
a blank dialog box that has non-functioning buttons. If a user closes
the dialog box window, it could unexpectedly grant the malicious web
page elevated privileges. (CVE-2011-0051)

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-2011-0053, CVE-2011-0055, CVE-2011-0058,
CVE-2011-0062)

Several flaws were found in the way Firefox handled malformed
JavaScript. A website containing malicious JavaScript could cause
Firefox to execute that JavaScript with the privileges of the user
running Firefox. (CVE-2011-0054, CVE-2011-0056, CVE-2011-0057)

A flaw was found in the way Firefox handled malformed JPEG images. A
website containing a malicious JPEG image could cause Firefox to crash
or, potentially, execute arbitrary code with the privileges of the
user running Firefox. (CVE-2011-0061)

A flaw was found in the way Firefox handled plug-ins that perform HTTP
requests. If a plug-in performed an HTTP request, and the server sent
a 307 redirect response, the plug-in was not notified, and the HTTP
request was forwarded. The forwarded request could contain custom
headers, which could result in a Cross Site Request Forgery attack.
(CVE-2011-0059)
