Tor 0.1.2.14 changes the addresses of two directory authorities (this change especially affects those who serve or use hidden services), and fixes several other crash- and security-related bugs. We'll put out 0.1.1.27 in the next week or so for people who absolutely can't upgrade -- but really, please upgrade to 0.1.2.14 if you can. Those still running 0.1.0.x should now consider it obsolete and unsupported. https://tor.eff.org/download.html Changes in version 0.1.2.14 - 2007-05-25 o Directory authority changes: - Two directory authorities (moria1 and moria2) just moved to new IP addresses. This change will particularly affect those who serve or use hidden services. o Major bugfixes (crashes): - If a directory server runs out of space in the connection table as it's processing a begin_dir request, it will free the exit stream but leave it attached to the circuit, leading to unpredictable behavior. (Reported by seeess, fixes bug 425.) - Fix a bug in dirserv_remove_invalid() that would cause authorities to corrupt memory under some really unlikely scenarios. - Tighten router parsing rules. (Bugs reported by Benedikt Boss.) - Avoid segfaults when reading from mmaped descriptor file. (Reported by lodger.) o Major bugfixes (security): - When choosing an entry guard for a circuit, avoid using guards that are in the same family as the chosen exit -- not just guards that are exactly the chosen exit. (Reported by lodger.) o Major bugfixes (resource management): - If a directory authority is down, skip it when deciding where to get networkstatus objects or descriptors. Otherwise we keep asking every 10 seconds forever. Fixes bug 384. - Count it as a failure if we fetch a valid network-status but we don't want to keep it. Otherwise we'll keep fetching it and keep not wanting to keep it. Fixes part of bug 422. - If all of our dirservers have given us bad or no networkstatuses lately, then stop hammering them once per minute even when we think they're failed. Fixes another part of bug 422. o Minor bugfixes: - Actually set the purpose correctly for descriptors inserted with purpose=controller. - When we have k non-v2 authorities in our DirServer config, we ignored the last k authorities in the list when updating our network-statuses. - Correctly back-off from requesting router descriptors that we are having a hard time downloading. - Read resolv.conf files correctly on platforms where read() returns partial results on small file reads. - Don't rebuild the entire router store every time we get 32K of routers: rebuild it when the journal gets very large, or when the gaps in the store get very large. o Minor features: - When routers publish SVN revisions in their router descriptors, authorities now include those versions correctly in networkstatus documents. - Warn when using a version of libevent before 1.3b to run a server on OSX or BSD: these versions interact badly with userspace threads.
