Red Hat Product Errata RHSA-2016:1551 0 normal SHIPPED_LIVE Critical: firefox security update 2016-08-03 12:06:43 UTC

Description Huzaifa S. Sidhpurwala 2016-08-01 06:26:52 UTC 
Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team reported a use-after-free vulnerability when the alt key is used in conjunction with toplevel menu items in Firefox. This results in a potentially exploitable crash when triggered. This vulnerability is mitigated by not being triggerable by web content, only direct user interaction with the keyboard.
