Package : ruby-rack
Version : 1.5.2-3+deb8u3
CVE ID : CVE-2020-8161

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.

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
