Integer overflow in the Array.reduceRight method in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code via vectors involving a long JavaScript Array object.

Security readout for executives and security teams

This flaw lets a malicious web page or HTML-capable content trigger memory corruption in older Mozilla products and potentially run code on the user's machine. It matters mainly for legacy systems still running affected Firefox, Thunderbird, or SeaMonkey versions. Exposure is most likely on obsolete desktops, embedded appliances, kiosks, or vendor bundles using Firefox before 3.6.18, Firefox 4.x through 4.0.1, Thunderbird before 3.1.11, or SeaMonkey through 2.0.14. Treat as high priority only where affected legacy software remains deployed. For modern managed endpoints, priority is asset discovery and confirmation rather than emergency response. Mitigation focus: Follow Mozilla MFSA-2011-22 and OS vendor advisories for fixed packages.; Remove or isolate unsupported Mozilla clients on legacy systems.; Inventory appliances or vendor products that bundled affected Mozilla components..
