Description (last modified by larryv (Lawrence Velázquez))

Tor backports a fix for a security hole in previous versions of Tor that would allow a remote attacker to crash a Tor client, hidden service, relay, or authority. All Tor users should upgrade to this version, or to Patches will be released for older versions of Tor.

  • Major features (security fixes):
    • Prevent a class of security bugs caused by treating the contents of a buffer chunk as if they were a NUL-terminated string. At least one such bug seems to be present in all currently used versions of Tor, and would allow an attacker to remotely crash most Tor instances, especially those compiled with extra compiler hardening. With this defense in place, such bugs can't crash Tor, though we should still fix them as they occur. Closes ticket 20384 (TROVE-2016-10-001).
