CVE-2006-3419: Tor

Medium severity, CVSS 5.0. EPSS: 1.7% chance of exploitation in the next 30 days.

Tor before 0.1.1.20 uses OpenSSL pseudo-random bytes (RAND_pseudo_bytes) instead of cryptographically strong RAND_bytes, and seeds the entropy value at start-up with 160-bit chunks without reseeding, which makes it easier for attackers to conduct brute force guessing attacks.
