Description

The ipsilon packages provide the Ipsilon identity provider service for federated single sign-on (SSO). Ipsilon links authentication providers and applications or utilities to allow for SSO. It includes a server and utilities to configure Apache-based service providers.

Security Fix(es):

  • A vulnerability was found in ipsilon in the SAML2 provider's handling of sessions. An attacker able to hit the logout URL could determine what service providers other users are logged in to and terminate their sessions. (CVE-2016-8638)
