tor 0.2.4.22 [bnc#878486] Tor was updated to the recommended version of the 0.2.4.x series.
major features in 0.2.4.x :
improved client resilience
support better link encryption with forward secrecy
new NTor circuit handshake
change relay queue for circuit create requests from size-based limit to time-based limit
many bug fixes and minor features
changes contained in 0.2.4.22: Backports numerous high-priority fixes. These include blocking all authority signing keys that may have been affected by the OpenSSL ‘heartbleed’ bug, choosing a far more secure set of TLS ciphersuites by default, closing a couple of memory leaks that could be used to run a target relay out of RAM.
Major features (security)
Block authority signing keys that were used on authorities vulnerable to the ‘heartbleed’ bug in OpenSSL (CVE-2014-0160).
Major bugfixes (security, OOM) :
Fix a memory leak that could occur if a microdescriptor parse fails during the tokenizing step.
Major bugfixes (TLS cipher selection) :
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.
includes changes from 0.2.4.21: Further improves security against potential adversaries who find breaking 1024-bit crypto doable, and backports several stability and robustness patches from the 0.2.5 branch.
Major features (client security) :
When we choose a path for a 3-hop circuit, make sure it contains at least one relay that supports the NTor circuit extension handshake. Otherwise, there is a chance that we’re building a circuit that’s worth attacking by an adversary who finds breaking 1024-bit crypto doable, and that chance changes the game theory.
Major bugfixes :
Do not treat streams that fail with reason END_STREAM_REASON_INTERNAL as indicating a definite circuit failure, since it could also indicate an ENETUNREACH connection error
includes changes from 0.2.4.20 :
Do not allow OpenSSL engines to replace the PRNG, even when HardwareAccel is set.
Fix assertion failure when AutomapHostsOnResolve yields an IPv6 address.
Avoid launching spurious extra circuits when a stream is pending.
packaging changes :
remove init script shadowing systemd unit
general cleanup
Add tor-fw-helper for UPnP port forwarding; not used by default
fix logrotate on systemd-only setups without init scripts, work tor-0.2.2.37-logrotate.patch to tor-0.2.4.x-logrotate.patch
verify source tarball signature
