Mandriva Linux Security Advisory : tor (MDVSA-2014:123)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

The remote Mandriva Linux host is missing a security update.

Description :

Updated tor packages fix multiple vulnerabilities :

Tor before, 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 solves these major and security problems :

- Block authority signing keys that were used on
authorities vulnerable to the heartbleed bug in OpenSSL

- 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

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