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

high Nessus Plugin ID 74481
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Mandriva Linux host is missing a security update.


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 (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.
