Debian DLA-982-1 : tor security update

high Nessus Plugin ID 100724

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It has been discovered that Tor, a connection-based low-latency anonymous communication system, contains a flaw in the hidden service code. A remote attacker can take advantage of this flaw to cause a hidden service to crash with an assertion failure (TROVE-2017-005).

For Debian 7 'Wheezy', this problem has been fixed in version 0.2.4.29-1.

We recommend that you upgrade your tor packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected tor, tor-dbg, and tor-geoipdb packages.
