Array index error in the (1) dtoa implementation in dtoa.c (aka pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c in libc, as used in multiple operating systems and products including in FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and other products, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large precision value in the format argument to a printf function, which triggers incorrect memory allocation and a heap-based buffer overflow during conversion to a floating-point number.

Security readout for executives and security teams

This is an old memory-safety flaw in floating-point formatting code used by several operating systems and applications. A specially crafted large precision value in printf-style formatting could crash affected software and may allow arbitrary code execution. Business urgency is mainly for legacy or embedded systems still carrying these vulnerable libraries or old browser/mail products. Exposure is most likely in unsupported legacy estates: FreeBSD 6.4/7.2, NetBSD 5.0, OpenBSD 4.5, Firefox before 3.0.15 or 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and products referenced by related vendor advisories. Treat as high priority where legacy platforms remain in production, especially internet-facing or user-facing software. For modern fully patched fleets, urgency is lower but still worth confirming because the flaw sits in shared libc-derived code. Mitigation focus: Inventory systems and applications for the affected OS and product versions listed in advisories.; Apply vendor security updates or upgrade away from unsupported affected releases.; Remove obsolete browsers and mail clients where patching is not practical..
