Mozilla has released Firefox 15, issuing patches for seven critical vulnerabilities. Updated for Mac OS X and other operating systems, Mozilla developers fixed 16 known security vulnerabilities including several memory safety bugs in the browser. According to the Mozilla Foundation security advisory 2012-57, “some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.”
The new Firefox 15 is said to be free from all known memory safety problems and potentially exploitable crashes that affect Firefox 14. Firefox 15 also comes with other enhancements, including a background update feature, which will allow the software to update automatically when new versions become available.
To get the latest version, you can update Firefox on your Mac by using the browser’s internal updater (go to Firefox > About Firefox > Check for Updates). You can also head over to this download page to get Firefox 15 on your Mac.
