Mozilla patched more than one vulnerability in Firefox when it updated the browser to version 3.6.2 on Monday, the company confirmed today.
A total of 10 flaws were fixed in Firefox 3.6.2, according to Mozilla's security advisory page, but details of others have been withheld until the company updates the older Firefox 3.0 and Firefox 3.5 browsers. Mozilla is scheduled to ship the updates, Firefox 3.0.19 and Firefox 3.5.9, next Tuesday, March 30.

Mozilla accelerated the release of Firefox 3.6.2 because a Russian researcher had announced a critical vulnerability in how the browser decodes the Web Open Font Format (WOFF), a Web-based font standard. Only Firefox 3.6 supports WOFF.
However, four of the vulnerabilities already patched in Firefox 3.6.2 also apply to older editions of the browser. One of the 10 fixed flaws that Mozilla ranked as "low" in its four step scoring system, one tagged as "high" and two marked as "critical."
Mozilla patched those bugs last month when it issued Firefox 3.0.18 and Firefox 3.5.8.
