Bumps rack from 2.1.2 to 2.2.3. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

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

Versions Affected: rack < 2.2.0 Not affected: Applications that do not use Rack::Directory. Fixed Versions: 2.1.3, >= 2.2.0

Impact

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.

Workarounds

Until such time as the patch is applied or their Rack version is upgraded, we recommend that developers do not use Rack::Directory in their

Percent-encoded cookies can be used to overwrite existing prefixed cookie names It is possible to forge a secure or host-only cookie prefix in Rack using an arbitrary cookie write by using URL encoding (percent-encoding) on the name of the cookie. This could result in an application that is dependent on this prefix to determine if a cookie is safe to process being manipulated into processing an insecure or cross-origin request. This vulnerability has been assigned the CVE identifier CVE-2020-8184.

Versions Affected: rack < 2.2.3, rack < 2.1.4 Not affected: Applications which do not rely on __Host- and __Secure- prefixes to determine if a cookie is safe to process Fixed Versions: rack >= 2.2.3, rack >= 2.1.4

Impact

An attacker may be able to trick a vulnerable application into processing an insecure (non-SSL) or cross-origin request if they can gain the ability to write arbitrary cookies that are sent to the application.
