- Clarify the manpage for the (deprecated) torify script. Closes
ticket 6892.
+Changes in version 0.3.0.8 - 2017-06-08
+ Tor 0.3.0.8 fixes a pair of bugs that would allow an attacker to
+ remotely crash a hidden service with an assertion failure. Anyone
+ running a hidden service should upgrade to this version, or to some
+ other version with fixes for TROVE-2017-004 and TROVE-2017-005.
+
+ Tor 0.3.0.8 also includes fixes for several key management bugs
+ that sometimes made relays unreliable, as well as several other
+ bugfixes described below.
+
+ o Major bugfixes (hidden service, relay, security, backport
+ from 0.3.1.3-alpha):
+ - Fix a remotely triggerable assertion failure when a hidden service
+ handles a malformed BEGIN cell. Fixes bug 22493, tracked as
+ TROVE-2017-004 and as CVE-2017-0375; bugfix on 0.3.0.1-alpha.
+ - Fix a remotely triggerable assertion failure caused by receiving a
+ BEGIN_DIR cell on a hidden service rendezvous circuit. Fixes bug
+ 22494, tracked as TROVE-2017-005 and CVE-2017-0376; bugfix
+ on 0.2.2.1-alpha.
+
+ o Major bugfixes (relay, link handshake, backport from 0.3.1.3-alpha):
+ - When performing the v3 link handshake on a TLS connection, report
+ that we have the x509 certificate that we actually used on that
+ connection, even if we have changed certificates since that
+ connection was first opened. Previously, we would claim to have
+ used our most recent x509 link certificate, which would sometimes
+ make the link handshake fail. Fixes one case of bug 22460; bugfix
+ on 0.2.3.6-alpha.
+
+ o Major bugfixes (relays, key management, backport from 0.3.1.3-alpha):
+ - Regenerate link and authentication certificates whenever the key
+ that signs them changes; also, regenerate link certificates
+ whenever the signed key changes. Previously, these processes were
+ only weakly coupled, and we relays could (for minutes to hours)
+ wind up with an inconsistent set of keys and certificates, which
+ other relays would not accept. Fixes two cases of bug 22460;
+ bugfix on 0.3.0.1-alpha.
+ - When sending an Ed25519 signing->link certificate in a CERTS cell,
+ send the certificate that matches the x509 certificate that we
+ used on the TLS connection. Previously, there was a race condition
+ if the TLS context rotated after we began the TLS handshake but
+ before we sent the CERTS cell. Fixes a case of bug 22460; bugfix
+ on 0.3.0.1-alpha.
+
+ o Major bugfixes (hidden service v3, backport from 0.3.1.1-alpha):
+ - Stop rejecting v3 hidden service descriptors because their size
+ did not match an old padding rule. Fixes bug 22447; bugfix on
+ tor-0.3.0.1-alpha.
+
+ o Minor features (fallback directory list, backport from 0.3.1.3-alpha):
+ - Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in
+ December 2016 (of which ~126 were still functional) with a list of
+ 151 fallbacks (32 new, 119 unchanged, 58 removed) generated in May
+ 2017. Resolves ticket 21564.
+
+ o Minor bugfixes (configuration, backport from 0.3.1.1-alpha):
+ - Do not crash when starting with LearnCircuitBuildTimeout 0. Fixes
+ bug 22252; bugfix on 0.2.9.3-alpha.
+
+ o Minor bugfixes (correctness, backport from 0.3.1.3-alpha):
+ - Avoid undefined behavior when parsing IPv6 entries from the geoip6
+ file. Fixes bug 22490; bugfix on 0.2.4.6-alpha.
+
+ o Minor bugfixes (link handshake, backport from 0.3.1.3-alpha):
+ - Lower the lifetime of the RSA->Ed25519 cross-certificate to six
+ months, and regenerate it when it is within one month of expiring.
+ Previously, we had generated this certificate at startup with a
+ ten-year lifetime, but that could lead to weird behavior when Tor
+ was started with a grossly inaccurate clock. Mitigates bug 22466;
+ mitigation on 0.3.0.1-alpha.
+
+ o Minor bugfixes (memory leak, directory authority, backport from
+ 0.3.1.2-alpha):
+ - When directory authorities reject a router descriptor due to
+ keypinning, free the router descriptor rather than leaking the
+ memory. Fixes bug 22370; bugfix on 0.2.7.2-alpha.
+
+
+Changes in version 0.2.9.11 - 2017-06-08
+ Tor 0.2.9.11 fixes a pair of bugs that would allow an attacker to
+ remotely crash a hidden service with an assertion failure. Anyone
+ running a hidden service should upgrade to this version, or to some
+ other version with fixes for TROVE-2017-004 and TROVE-2017-005.
+
+ Tor 0.2.9.11 also backports fixes for several key management bugs
+ that sometimes made relays unreliable, as well as several other
+ bugfixes described below.
+
+ o Major bugfixes (hidden service, relay, security, backport
+ from 0.3.1.3-alpha):
+ - Fix a remotely triggerable assertion failure caused by receiving a
+ BEGIN_DIR cell on a hidden service rendezvous circuit. Fixes bug
+ 22494, tracked as TROVE-2017-005 and CVE-2017-0376; bugfix
+ on 0.2.2.1-alpha.

+ - Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in
+ December 2016 (of which ~126 were still functional) with a list of
+ 151 fallbacks (32 new, 119 unchanged, 58 removed) generated in May
+ 2017. Resolves ticket 21564.
+
+ o Minor features (future-proofing, backport from 0.3.0.7):
+ - Tor no longer refuses to download microdescriptors or descriptors if
+ they are listed as "published in the future". This change will
+ eventually allow us to stop listing meaningful "published" dates
+ in microdescriptor consensuses, and thereby allow us to reduce the
+ resources required to download consensus diffs by over 50%.
+ Implements part of ticket 21642; implements part of proposal 275.
+
+ o Minor features (directory authorities, backport from 0.3.0.4-rc)
+ - Directory authorities now reject relays running versions
+ 0.2.9.1-alpha through 0.2.9.4-alpha, because those relays
+ suffer from bug 20499 and don't keep their consensus cache
+ up-to-date. Resolves ticket 20509.
+
+ o Minor features (geoip):
+ - Update geoip and geoip6 to the May 2 2017 Maxmind GeoLite2
+ Country database.
+
+ o Minor bugfixes (control port, backport from 0.3.0.6):
+ - The GETINFO extra-info/digest/<digest> command was broken because
+ of a wrong base16 decode return value check, introduced when
+ refactoring that API. Fixes bug 22034; bugfix on 0.2.9.1-alpha.
+
+ o Minor bugfixes (correctness, backport from 0.3.1.3-alpha):
+ - Avoid undefined behavior when parsing IPv6 entries from the geoip6
+ file. Fixes bug 22490; bugfix on 0.2.4.6-alpha.
+
+ o Minor bugfixes (Linux seccomp2 sandbox, backport from 0.3.0.7):
+ - The getpid() system call is now permitted under the Linux seccomp2
+ sandbox, to avoid crashing with versions of OpenSSL (and other
+ libraries) that attempt to learn the process's PID by using the
+ syscall rather than the VDSO code. Fixes bug 21943; bugfix
+ on 0.2.5.1-alpha.
+
+ o Minor bugfixes (memory leak, directory authority, backport
+ from 0.3.1.2-alpha):
+ - When directory authorities reject a router descriptor due to
+ keypinning, free the router descriptor rather than leaking the
+ memory. Fixes bug 22370; bugfix on 0.2.7.2-alpha.
