Description Huzaifa S. Sidhpurwala 2016-08-01 06:28:31 UTC
Security researcher Jukka Jylänki reported a use-after-free in JavaScript caused by how objects and pointers are handled during incremental garbage collection in some circumstances working with object groups. When triggered, this causes a potential exploitable crash but is mitigated by the difficulties in controlling the crash and its output.
