Ubuntu 16.04 ESM / 18.04 ESM : Tinyproxy vulnerability (USN-4808-1)

medium Nessus Plugin ID 183157

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-4808-1 advisory.

 - main.c in Tinyproxy 1.8.4 and earlier creates a /run/tinyproxy/tinyproxy.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for tinyproxy.pid modification before a root script executes a kill `cat /run/tinyproxy/tinyproxy.pid` command. (CVE-2017-11747)

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

Solution

Update the affected tinyproxy and / or tinyproxy-bin packages.
