The asm.js implementation in Mozilla Firefox before 38.0 does not properly determine heap lengths during identification of cases in which bounds checking may be safely skipped, which allows remote attackers to trigger out-of-bounds write operations and possibly execute arbitrary code, or trigger out-of-bounds read operations and possibly obtain sensitive information from process memory, via crafted JavaScript.

Security readout for executives and security teams

A flaw in Firefox's asm.js JavaScript engine before version 38.0 could let a malicious web page cause memory corruption. The stated impacts include possible arbitrary code execution or reading sensitive process memory. This mainly matters for organizations still running legacy Firefox or vendor-packaged Mozilla components. Exposure is likely limited to Firefox versions before 38.0 and historical vendor-packaged Mozilla builds referenced by Ubuntu, openSUSE, Gentoo, and Oracle advisories. Modern environments should mainly verify no legacy browsers remain. Treat as high priority only where legacy Firefox or old vendor Mozilla packages still exist. For current managed fleets, the priority is confirmation and cleanup rather than emergency response. Mitigation focus: Upgrade Firefox to version 38.0 or later.; Apply relevant Ubuntu, openSUSE, Gentoo, or Oracle security updates.; Remove unsupported legacy Firefox installations from endpoints and images..
