How to fix?

Upgrade tor to version 0.2.8.9 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. Tor before 0.2.8.9 and 0.2.9.x before 0.2.9.4-alpha had internal functions that were entitled to expect that buf_t data had NUL termination, but the implementation of or/buffers.c did not ensure that NUL termination was present, which allows remote attackers to cause a denial of service (client, hidden service, relay, or authority crash) via crafted data.
