                   CVE-2010-3183

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-2010-3175, CVE-2010-3176, CVE-2010-3179, 
CVE-2010-3183, CVE-2010-3180)

A flaw was found in the way the Gopher parser in Firefox converted text
into HTML. A malformed file name on a Gopher server could, when accessed 
by a victim running Firefox, allow arbitrary JavaScript to be executed 
in the context of the Gopher domain. (CVE-2010-3177)

A same-origin policy bypass flaw was found in Firefox. An attacker could
create a malicious web page that, when viewed by a victim, could steal
private data from a different website the victim has loaded with 
Firefox. (CVE-2010-3178)

A flaw was found in the script that launches Firefox. The 
LD_LIBRARY_PATH variable was appending a "." character, which could 
allow a local attacker to execute arbitrary code with the privileges of 
a different user running Firefox, if that user ran Firefox from within 
an attacker-controlled directory. (CVE-2010-3182)

This update also provides NSS version 3.12.8 which is required by the
updated Firefox version, fixing the following security issues:

It was found that the SSL DHE (Diffie-Hellman Ephemeral) mode
implementation for key exchanges in Firefox accepted DHE keys that were 
256 bits in length. This update removes support for 256 bit DHE keys, as 
such keys are easily broken using modern hardware. (CVE-2010-3173)

A flaw was found in the way NSS matched SSL certificates when the
certificates had a Common Name containing a wildcard and a partial IP
address. NSS incorrectly accepted connections to IP addresses that fell
within the SSL certificate's wildcard range as valid SSL connections,
possibly allowing an attacker to conduct a man-in-the-middle attack.
(CVE-2010-3170)


After installing the update, Firefox must be restarted for the changes 
to take effect.
