The fence-agents packages provide a collection of scripts for handling remote power management for cluster devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.

Security Fix(es):

* python-oauthlib: DoS when attacker provides malicious IPV6 URI (CVE-2022-36087)

Affected: Homebrew: ansible

### Impact - Attacker providing malicious redirect uri can cause DoS to oauthlib's web application. - Attacker can also leverage usage of `uri_validate` functions depending where it is used.

_What kind of vulnerability is it? Who is impacted?_

Oauthlib applications using OAuth2.0 provider support or use directly `uri_validate` function.

### Patches _Has the problem been patched? What versions should users upgrade to?_

Issue fixed in 3.2.2 release.

### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_

The `redirect_uri` can be verified in web toolkit (i.e `bottle-oauthlib`, `django-oauth-toolkit`, ...) before oauthlib is called. A sample check if `:` is present to reject the request can prevent the DoS, assuming no port or IPv6 is fundamentally required.

OAuthLib is an implementation of the OAuth request-signing logic for Python 3.6+. In OAuthLib versions 3.1.1 until 3.2.1, an attacker providing malicious redirect uri can cause denial of service. An attacker can also leverage usage of `uri_validate` functions depending where it is used. OAuthLib applications using OAuth2.0 provider support or use directly `uri_validate` are affected by this issue. Version 3.2.1 contains a patch. There are no known workarounds.
