Mozilla has released the first update for the Firefox 2.0 browser. The latest version fixes eight security vulnerabilities.

According to the company, Firefox 2.0.0.1 fixes flaws in memory corruption as well as the way the browser executes RSS (really simple syndication), Javascript and CSS (cascading style sheets) code, among other vulnerabilities. Mozilla also patched similar flaws in its Firefox 1.5 browser.

Five of the eight flaws were rated as 'critical', according to Firefox. A critical rating means a Firefox user would be vulnerable to attack and remote software installation just from browsing the web in the usual fashion. Two of the flaws were rated as 'high', while one received a 'low' security risk rating, Firefox said.

Mozilla's advisory and information on the update can be found on the company's website.

Danish security firm Secunia ApS has also posted information about the patches. Visit the Secunia website to find out more.

Mozilla released Firefox 2.0, the second major update to its open-source browser, in October.
