CVE-2016-7544: Crypto++ 5.6.4 incorrectly uses Microsoft's stack-based _malloca and _freea functions.

Security readout for executives and security teams

Crypto++ 5.6.4 can mishandle temporary memory on Microsoft compiler builds. In affected cases, the library may free the wrong pointer after reallocating an aligned table. The supplied sources do not provide CVSS, confirmed impact severity, or evidence of exploitation. Exposure is most likely in applications statically or dynamically using Crypto++ 5.6.4 built with Microsoft compilers. The bundle does not identify downstream products or package ecosystems, so exposure must be confirmed from software inventories and build records. Handle through dependency risk management rather than emergency response. Prioritize systems using Crypto++ 5.6.4 in Windows or Microsoft compiler contexts, especially where cryptographic processing is exposed to untrusted input. Mitigation focus: Inventory applications and third-party components using Crypto++ 5.6.4.; Prioritize Microsoft compiler builds for review.; Review Crypto++ 5.6.5 release notes and vendor guidance..
