Description

Tor before 0.2.4.20, when OpenSSL 1.x is used in conjunction with a certain HardwareAccel setting on Intel Sandy Bridge and Ivy Bridge platforms, does not properly generate random numbers for (1) relay identity keys and (2) hidden-service identity keys, which might make it easier for remote attackers to bypass cryptographic protection mechanisms via unspecified vectors.

Affected products

torproject Tor: through 0.2.4.19; 0.2.4.1-alpha, 0.2.4.2-alpha, 0.2.4.3-alpha, 0.2.4.4-alpha, 0.2.4.5-alpha, 0.2.4.6-alpha (+12)
