RHEL 7 : ipsilon (RHSA-2016:2809)

critical Nessus Plugin ID 95047

Language:

Synopsis

The remote Red Hat host is missing a security update for ipsilon.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2809 advisory.

 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)

 This issue was discovered by Patrick Uiterwijk (Red Hat) and Howard Johnson.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL ipsilon package based on the guidance in RHSA-2016:2809.
