A Ruby library for verifying and serving OpenID identities.
It was discovered that OpenID library for Ruby performed discovery first, and then verification.
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.
There is no known workaround at this time.
All ruby-openid users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/ruby-openid-2.9.2"
OS | Version | Architecture | Package | Version | Filename |
