• Severity: medium (CVSS 5.0 v2.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.7% probability of exploitation in the next 30 days

Description

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.

Affected products

• Tor: 0.0.2, 0.0.2_pre13, 0.0.2_pre14, 0.0.2_pre15, 0.0.2_pre16, 0.0.2_pre17 (+62)
