Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A signature-validation bypass issue was discovered in SimpleSAMLphp through 1.14.16. A SimpleSAMLphp
 Service Provider using SAML 1.1 will regard as valid any unsigned SAML response containing more than one
 signed assertion, provided that the signature of at least one of the assertions is valid. Attributes
 contained in all the assertions received will be merged and the entityID of the first assertion received
 will be used, allowing an attacker to impersonate any user of any IdP given an assertion signed by the
 targeted IdP. (CVE-2017-18122)
