Mozilla Firefox has just released version 3.5.6 on December 15th. This update of the open-source browser sews up security and stability issues, resolving three critical security holes, and also patches up other stability issues. The three flaws that this update rectifies:
1. An integer overflow flaw in the libtheora video library
2. A memory Safety concern in the liboggplay media library
Please see Mozilla’s list of security advisories for a full list on the critical fixes and more details.
The moral of this post: When your Firefox browser prompts you to install some updates, please do so!
