Description

This security bulletin contains information about 3 secuirty vulnerabilities.


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.


2) Input validation error (CVE-ID: CVE-2012-2249)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Tor before 0.2.3.23-rc allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a renegotiation attempt that occurs after the initiation of the V3 link protocol.


3) Input validation error (CVE-ID: CVE-2012-2250)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Tor before 0.2.3.24-rc allows remote attackers to cause a denial of service (assertion failure and daemon exit) by performing link protocol negotiation incorrectly.
