With its most recent Firefox 3.6 version already secured, Mozilla unveils a number of new security improvements to older versions of its popular open source browser. eSecurity Planet details the new patches and some of the critical vulnerabilities addressed with these updates.
Mozilla has released an update for two older versions of its popular Firefox Web browser, offering a trio of critical fixes and bumping the Firefox 3.0.x and 3.5.x releases to 3.0.18 and Firefox 3.5.8, respectively.
Users of the more recent Firefox 3.6 have nothing to worry about, though, since their browser was fixed last month for the same issues now affecting the two older versions.
Mozilla typically continues to support its older browser releases with security fixes for at least six months after a new numbered browser release. Mozilla released Firefox 3.6 at the end of January, with the new version being made available as an update option for Firefox 3.5.7 users.
In total, the new Firefox 3.5.8 and 3.0.18 updates deliver five key security fixes, three rated by Mozilla as being critical in severity, and two rated as moderate.
On the critical side is a fix for crashes that potentially could have led to memory corruption issues
