"ruby-openid performed discovery first, and then verification. This
allowed an attacker to change the URL used for discovery and trick the
server into connecting to the URL. This server in turn could be a
private server not publicly accessible.

Furthermore, if the client that uses this library discloses connection
errors, this in turn could disclose information from the private
server to the attacker.

For Debian 8 'Jessie', this problem has been fixed in version
2.5.0debian-1+deb8u1.

We recommend that you upgrade your ruby-openid packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."

(OpenID library for Ruby: Server-Side Request Forgery)

    It was discovered that OpenID library for Ruby performed discovery
      first, and then verification.
  
Impact :

    A remote attacker could possibly change the URL used for discovery and
      trick the server into connecting to the URL. This server in turn could be
      a private server not
      publicly accessible.
    In addition, if the client that uses this library discloses connection
      errors, this in turn could disclose information from the private server
      to the attacker.
  
Workaround :

    There is no known workaround at this time."
