CVE-2016-7420 Information

Description

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.
