Last modified

CVE-2013-7295 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.75% chance of exploitation in the next 30 days.
