FreeBSD : Tor -- remote denial of service (c1dc55dc-9556-11e6-b154-3065ec8fd3ec)

high Nessus Plugin ID 94127

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Tor Blog reports :

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).

Solution

Update the affected packages.
