🚨 [security] Update rack: 2.0.6 → 2.1.3 (minor) #243

Closed depfu[bot] closed 4 years ago

depfu[bot] commented 4 years ago

🚨 Your version of rack has known security vulnerabilities 🚨

Advisory: CVE-2020-8161 Disclosed: May 12, 2020 URL: https://groups.google.com/forum/#!topic/ruby-security-ann/T4ZIsfRf2eA

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
applications.


🚨 We recommend to merge and deploy this update as soon as possible! 🚨

Here is everything you need to know about this update. Please take a good look at what changed and the test results before merging this pull request.
