Tor 0.2.9.9 发布了。Tor 通过隐藏网址与你所使用的服务器的连接来保护隐私安全。
- Major bugfixes (security):
- Downgrade the “-ftrapv” option from “always on” to “only on when –enable-expensive-hardening is provided.” This hardening option, like others, can turn survivable bugs into crashes — and having it on by default made a (relatively harmless) integer overflow bug into a denial-of-service bug. Fixes bug 21278 (TROVE-2017-001); bugfix on 0.2.9.1-alpha.
- 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 mysterious “Remote server sent bogus reason code 65021″ log warning. The bug was introduced in ticket 17218, where we tried to remember the circuit end reason as a uint16_t, which mangled negative values. Partially fixes bug 21056 and fixes bug 20307; bugfix on 0.2.8.1-alpha.
