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.
