Firefox releases Version 5; five remote code vulnerabilities fixed

* MFSA 2011-26 Multiple WebGL crashes
* MFSA 2011-22 Integer overflow and arbitrary code execution in Array.reduceRight()
* MFSA 2011-21 Memory corruption due to multipart/x-mixed-replace images
* MFSA 2011-20 Use-after-free vulnerability when viewing XUL document with script disabled
* MFSA 2011-19 Miscellaneous memory safety hazards (rv:3.0/1.9.2.18)

 

Mozilla delivered on its promise to have the Version 5 release of its browser ready by midwinter's day, which takes place today in Australia – 22 June 2011.

The new version officially calls itself 5.0, but the Version 4 release is just three months old, and has had only one point update (to Version 4.0.1).

It looks as though Mozilla is simply copying Google's Chrome version numbering system in order to seem more "with it."
