According to the version of the ipsilon packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • 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)

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