Several vulnerabilities have been discovered in SimpleSAMLphp, a framework for authentication, primarily via the SAML protocol.

  - CVE-2017-12867     Attackers with access to a secret token could extend its     validity period by manipulating the prepended time     offset.

  - CVE-2017-12869     When using the multiauth module, attackers can bypass     authentication context restrictions and use any     authentication source defined in the config.

  - CVE-2017-12873     Defensive measures have been taken to prevent the     administrator from misconfiguring persistent NameIDs to     avoid identifier clash. (Affects Debian 8 Jessie only.)

  - CVE-2017-12874     The InfoCard module could accept incorrectly signed XML     messages in rare occasions.

  - CVE-2017-18121     The consentAdmin module was vulnerable to a Cross-Site     Scripting attack, allowing an attacker to craft links     that could execute arbitrary JavaScript code in the     victim's browser.

  - CVE-2017-18122     The (deprecated) SAML 1.1 implementation would regard as     valid any unsigned SAML response containing more than     one signed assertion, provided that the signature of at     least one of the assertions was valid, allowing an     attacker that could obtain a valid signed assertion from     an IdP to impersonate users from that IdP.

  - CVE-2018-6519     Regular expression denial of service when parsing     extraordinarily long timestamps.

  - CVE-2018-6521     Change sqlauth module MySQL charset from utf8 to utf8mb     to prevent theoretical query truncation that could allow     remote attackers to bypass intended access restrictions

  - CVE-2018-7644     Critical signature validation vulnerability.
