AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Crypto++ versions through 5.6.4

Description The issue concerns the lack of documentation for a compile-time definition that disables assert calls, potentially allowing attackers to obtain sensitive information from process memory after an assertion failure. This could be exploited by accessing a core dump after such a failure.

Recommendations For Crypto++ versions through 5.6.4, define NDEBUG at compile-time to disable assert calls and prevent potential information disclosure.
