NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The js::jit::AssemblerX86Shared::lock_addl function in the JavaScript implementation in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to cause a denial of service (application crash) by leveraging the use of shared memory and accessing (1) an Atomics object or (2) a SharedArrayBuffer object.
