Changes in version 0.3.0.2-alpha - 2017-01-23
Tor 0.3.0.2-alpha fixes a denial-of-service bug where an attacker could
- cause relays and clients (including hidden services) to crash, even if
- they were not built with the --enable-expensive-hardening option.
- This bug affects all 0.2.9.x versions, and also affects 0.3.0.1-alpha:
- all relays running an affected version should upgrade.

+ Tor 0.2.9.9 fixes a denial-of-service bug where an attacker could
+ cause relays and clients to crash, even if they were not built with
+ the --enable-expensive-hardening option. This bug affects all 0.2.9.x

+ - Downgrade the "-ftrapv" option from "always on" to "only on when
+ --enable-expensive-hardening is provided." This hardening option,

+ it on by default made a (relatively harmless) integer overflow bug
+ into a denial-of-service bug. Fixes bug 21278 (TROVE-2017-001);

+
+ o Major bugfixes (client, onion service):
+ - Fix a client-side onion service reachability bug, where multiple
+ socks requests to an onion service (or a single slow request)
+ could cause us to mistakenly mark some of the service's
+ introduction points as failed, and we cache that failure so
+ eventually we run out and can't reach the service. Also resolves a

+ remember the circuit end reason as a uint16_t, which mangled
+ negative values. Partially fixes bug 21056 and fixes bug 20307;

+ - Avoid crashing when Tor is built using headers that contain
+ CLOCK_MONOTONIC_COARSE, but then tries to run on an older kernel
+ without CLOCK_MONOTONIC_COARSE. Fixes bug 21035; bugfix
