Hi,

The following vulnerability was published for ruby-openid.

CVE-2019-11027[0]:
| Ruby OpenID (aka ruby-openid) through 2.8.0 has a remotely exploitable
| flaw. This library is used by Rails web applications to integrate with
| OpenID Providers. Severity can range from medium to critical,
| depending on how a web application developer chose to employ the ruby-
| openid library. Developers who based their OpenID integration heavily
| on the "example app" provided by the project are at highest risk.

Unfortunately there very scarce information available for this issue.
SuSE folks did try to ask upstream in [1]. Originally the assignement
seems to come from [2], but this as well does practiaclly not give
enough information.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
