<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>simplesamlphp, an authentication and federation application has been
found vulnerable to Cross Site Scripting (XSS), signature validation
byepass and using insecure connection charset.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2017-18121">CVE-2017-18121</a>
<p>A Cross Site Scripting (XSS) issue has been found in the
consentAdmin module of SimpleSAMLphp through 1.14.15, allowing an
attacker to manually craft links that a victim can open, executing
arbitrary javascript code.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2017-18122">CVE-2017-18122</a>
<p>A signature-validation bypass issue was discovered in SimpleSAMLphp
through 1.14.16. 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.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-6521">CVE-2018-6521</a>
<p>The sqlauth module in SimpleSAMLphp before 1.15.2 relies on the
MySQL utf8 charset, which truncates queries upon encountering
four-byte characters. There might be a scenario in which this allows
remote attackers to bypass intended access restrictions.</p></li>
</ul>
<p>For Debian 7 <q>Wheezy</q>, these problems have been fixed in version
1.9.2-1+deb7u2.</p>
<p>We recommend that you upgrade your simplesamlphp packages.</p>

these updates to your system and frequently asked questions can be
