Description Andreas Stieger 2016-04-27 08:55:31 UTC 
https://www.mozilla.org/en-US/security/advisories/mfsa2016-47/

The CESG, the Information Security Arm of GCHQ, reported that the JavaScript .watch() method could be used to overflow the 32-bit generation count of the underlying HashMap, resulting in a write to an invalid entry. Under the right conditions this write could lead to arbitrary code execution. The overflow takes considerable time and a malicious page would require a user to keep it open for the duration of the attack. 

null-byte written out of bounds using .watch() due to generation count overflow (CVE-2016-2808)
