It is recommended that administrators running ruby-openid check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Package : ruby-openid Version : 2.5.0debian-1+deb8u1 CVE ID : CVE-2019-11027 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.
