New security updates for Firefox 2 and 3

Mozilla has pushed out updates to Firefox versions 2 and 3 to shore up 20 vulnerabilities, some of which could be exploited to launch remote code attacks.

Firefox 2.0.0.18 contains updates for 11 flaws -- six labeled critical, while Firefox 3.0.4 closes nine flaws -- four deemed critical.

The vulnerabilities could be exploited to execute a range of attacks, including arbitrary code injection, privilege escalation, cross-site scripting, denial-of-service, security bypass and information disclosure, according to a US-CERT alert.

Also on Wednesday, Mozilla released a new version of its open-source internet suite, SeaMonkey, which comes outfitted with the same fixes as Firefox 2.0.0.18.

Users are advised to upgrade to Firefox 3, as Mozilla plans to cut support for Firefox 2 around mid-December.
