Debian DSA-5320-1 : tor - security update

medium Nessus Plugin ID 170105

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5320 advisory.

A logic error was discovered in the implementation of the SafeSocks option of Tor, a connection-based low- latency anonymous communication system, which did result in allowing unsafe SOCKS4 traffic to pass. For the stable distribution (bullseye), this problem has been fixed in version 0.4.5.16-1. We recommend that you upgrade your tor packages. For the detailed security status of tor please refer to its security tracker page at: https://security-tracker.debian.org/tracker/tor

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the tor packages.

For the stable distribution (bullseye), this problem has been fixed in version 0.4.5.16-1.
