Download our in-depth report: The Ultimate Guide to IT Security VendorsMozilla has updated its now legacy 1.5.x Firefox browser to version 22.214.171.124, with fixes for three critical security flaws.
The flaws do not affect the recently released Firefox 2.0 version. The latest 126.96.36.199 release will also include an update that will make it easier for existing users to get major upgrades from Mozilla.
Among the critical bugs fixed in this version is titled, "Crashes with evidence of memory corruption." The crashes could have been triggered by several bugs. Mozilla's analysis: there was potential for memory corruption that potentially could have been exploited to run arbitrary code.
One of the issues for some 1.5.x users that have prevented them from upgrading to Firefox 2.0 is that, to date, Firefox 1.5.x has not "advertised" that it can be updated to version 2.0.
