Mandriva Linux Security Advisory MDVSA-2014:123
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : tor
Date : June 11, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated tor packages fix multiple vulnerabilities:

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 relay identity
keys and hidden-service identity keys, which might make it easier
for remote attackers to bypass cryptographic protection mechanisms
via unspecified vectors (CVE-2013-7295).

Update to version 0.2.4.22 solves these major and security problems:

- Block authority signing keys that were used on authorities vulnerable
to the heartbleed bug in OpenSSL (CVE-2014-0160).

- Fix a memory leak that could occur if a microdescriptor parse fails
during the tokenizing step.

- The relay ciphersuite list is now generated automatically based on
uniform criteria, and includes all OpenSSL ciphersuites with acceptable
strength and forward secrecy.

- Relays now trust themselves to have a better view than clients of
which TLS ciphersuites are better than others.

- Clients now try to advertise the same list of ciphersuites as
Firefox 28.
