FKIE_CVE-2007-5502

Vulnerability from fkie_nvd - Published: 2007-12-01 06:46 - Updated: 2026-06-16 22:46
Severity
Summary
The PRNG implementation for the OpenSSL FIPS Object Module 1.1.1 does not perform auto-seeding during the FIPS self-test, which generates random data that is more predictable than expected and makes it easier for attackers to bypass protection mechanisms that rely on the randomness.
