Home Business IT Open Source Firefox 3.6.2 arrives sooner than expected

An update for the popular Firefox open source browser fixes a critical security bug.


As previously reported, Firefox 3.6 contained a remotely exploitable security vulnerability that was publicised in February by Secunia following its discovery by security researcher Evgeny Legerov.

For some reason, Legerov did not immediately provide Mozilla with details. Once he did, the flaw was fixed as part of Firefox 3.6.2 which has now been released about a week earlier than expected.

The vulnerability involved an integer overflow condition in the WOFF (Web Open Font Format) decoder that was new in version 1.9.2 of the Gecko engine and therefore affected Firefox 3.6 only, not other Mozilla programs.

Mozilla confirmed that the vulnerability could allow the execution of arbitrary code.

Firefox 3.6.2 also includes a long list of fixes for stability and other issues.

Windows and Mac OS X users can most easily get version 3.6.2 by using the Check for Updates command in Firefox 3.6. The complete program can be downloaded here.
