Description
This security bulletin contains information about 1 security vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2013-7295)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
