CVE-2016-7420: Crypto++ (aka cryptopp) through 5.6.4 does not document the requirement for a compile-time NDEBUG definitio...

Security readout for executives and security teams

Crypto++ through 5.6.4 had unclear production build guidance: assertions should be disabled with NDEBUG. If assertions remain enabled and a failure produces process memory artifacts such as core dumps, sensitive cryptographic data may be exposed to someone who can access those artifacts. Exposure is likely limited to applications using Crypto++ through 5.6.4, built without NDEBUG, running in production, and configured to preserve accessible core dumps or memory snapshots. Treat this as a targeted hardening and exposure-review item, not an emergency patch event. Prioritize internet-facing or sensitive-data services using old Crypto++ builds. Mitigation focus: Check whether production builds define NDEBUG for Crypto++ code.; Follow Crypto++ vendor guidance and the linked documentation change.; Upgrade Crypto++ if vendor guidance recommends a newer maintained release..
