FKIE_CVE-2013-7295

Vulnerability from fkie_nvd - Published: 2014-01-17 21:55 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
