+Changes in version 0.3.1.3-alpha - 2017-06-08
|
|
|
+ Tor 0.3.1.3-alpha 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 0.3.1.3-alpha also includes fixes for several key management bugs
|
|
|
+ that sometimes made relays unreliable, as well as several other
|
|
|
+ bugfixes described below.
|
|
|
+
|
|
|
+ o Major bugfixes (relay, link handshake):
|
|
|
+ - 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):
|
|
|
+ - 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 (torrc, crash):
|
|
|
+ - Fix a crash bug when using %include in torrc. Fixes bug 22417;
|
|
|
+ bugfix on 0.3.1.1-alpha. Patch by Daniel Pinto.
|
|
|
+
|
|
|
+ o Minor features (code style):
|
|
|
+ - Add "Falls through" comments to our codebase, in order to silence
|
|
|
+ GCC 7's -Wimplicit-fallthrough warnings. Patch from Andreas
|
|
|
+ Stieger. Closes ticket 22446.
|
|
|
|
|
|
+ o Minor features (diagnostic):
|
|
|
+ - Add logging messages to try to diagnose a rare bug that seems to
|
|
|
+ generate RSA->Ed25519 cross-certificates dated in the 1970s. We
|
|
|
+ think this is happening because of incorrect system clocks, but
|
|
|
+ we'd like to know for certain. Diagnostic for bug 22466.
|
|
|
+
|
|
|
+ o Minor bugfixes (correctness):
|
|
|
+ - Avoid undefined behavior when parsing IPv6 entries from the geoip6
|
|
|
+ file. Fixes bug 22490; bugfix on 0.2.4.6-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (directory protocol):
|
|
|
+ - Check for libzstd >= 1.1, because older versions lack the
|
|
|
+ necessary streaming API. Fixes bug 22413; bugfix on 0.3.1.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (link handshake):
|
|
|
+ - 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 (storage directories):
|
|
|
+ - Always check for underflows in the cached storage directory usage.
|
|
|
+ If the usage does underflow, re-calculate it. Also, avoid a
|
|
|
+ separate underflow when the usage is not known. Fixes bug 22424;
|
|
|
+ bugfix on 0.3.1.1-alpha.
|
|
|
|
|
|
+ o Minor bugfixes (unit tests):
|
|
|
+ - The unit tests now pass on systems where localhost is misconfigured
|
|
|
+ to some IPv4 address other than 127.0.0.1. Fixes bug 6298; bugfix
|
|
|
+ on 0.0.9pre2.
|
|
|
+
|
|
|
+ o Documentation:
|
|
|
+ - Clarify the manpage for the (deprecated) torify script. Closes
|
|
|
+ ticket 6892.
