Mozilla has released the first update for the Firefox 2.0 browser to fix eight security vulnerabilities.
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 on their machines 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 Web site.
Danish security firm Secunia ApS also posted information about the patches on its Web site.
Mozilla released Firefox 2.0, the second major update to its open-source browser, in October.
