-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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.
