Package : rails
Version : 2:5.2.2.1+dfsg-1+deb10u4
CVE ID : CVE-2022-21831 CVE-2022-22577 CVE-2022-23633 CVE-2022-27777
CVE-2022-32224

The following vulnerabilities have been discovered in rails, a ruby
based MVC frame work for web development.

CVE-2022-21831

A code injection vulnerability exists in the Active Storage that
could allow an attacker to execute code via image_processing
arguments.

CVE-2022-22577

An XSS Vulnerability in Action Pack that could allow an attacker
to bypass CSP for non HTML like responses.

CVE-2022-23633

Action Pack is a framework for handling and responding to web
requests. Under certain circumstances response bodies will not be
closed. In the event a response is *not* notified of a `close`,
`ActionDispatch::Executor` will not know to reset thread local
state for the next request. This can lead to data being leaked to
subsequent requests.

CVE-2022-27777

A XSS Vulnerability in Action View tag helpers which would allow
an attacker to inject content if able to control input into
specific attributes.

CVE-2022-32224

When serialized columns that use YAML (the default) are
deserialized, Rails uses YAML.unsafe_load to convert the YAML data
in to Ruby objects. If an attacker can manipulate data in the
database (via means like SQL injection), then it may be possible
for the attacker to escalate to an RCE.

For Debian 10 buster, these problems have been fixed in version
2:5.2.2.1+dfsg-1+deb10u4.

We recommend that you upgrade your rails packages.
