libcrypto++: CVE-2016-7420

Severity: Medium · CVSS 4CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

Crypto++ (aka cryptopp) through 5.6.4 does not document the requirement for a compile-time NDEBUG definition disabling the many assert calls that are unintended in production use, which might allow context-dependent attackers to obtain sensitive information by leveraging access to process memory after an assertion failure, as demonstrated by reading a core dump.
