Package        : simplesamlphp
Version        : 1.9.2-1+deb7u3
CVE ID         : CVE-2016-9814 CVE-2016-9955

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

CVE-2016-9814 & CVE-2016-9955

    An incorrect check of return values in the signature validation
    utilities allowed an attacker to get invalid signatures accepted
    as valid in the rare case of an error occurring during validation.

SSPSA-201802-01 (no CVE yet)

    Critical signature validation vulnerability.

In addition this update adds a patch to solve excessive resource
consumption in case of SimpleSAMLphp processing a large metadata file.

For Debian 7 "Wheezy", these problems have been fixed in version
1.9.2-1+deb7u3.

We recommend that you upgrade your simplesamlphp packages.
