Description Prasad Pandit 2015-09-22 10:53:16 UTC

Mozilla developers and community identified and fixed several memory safety
bugs in the browser engine used in Firefox and other Mozilla-based products.
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.
