CVE-2016-7420

MEDIUM

Cryptopp Crypto++ < 5.6.4 - Information Disclosure

Title source: rule

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.
