Debian DLA-2216-1 : ruby-rack security update

high Nessus Plugin ID 136832

Language:

Synopsis

The remote Debian host is missing a security update.

Description

There was a possible directory traversal vulnerability in the Rack::Directory app that is bundled with Rack.

If certain directories exist in a director that is managed by `Rack::Directory`, an attacker could, using this vulnerability, read the contents of files on the server that were outside of the root specified in the Rack::Directory initializer.

For Debian 8 'Jessie', this problem has been fixed in version 1.5.2-3+deb8u3.

We recommend that you upgrade your ruby-rack 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 ruby-rack package.
