<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>

<p>Several issues have been found in libapache2-mod-auth-openidc, the OpenID
Connect authentication module for the Apache HTTP server.</p>

<ul>

<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-14857">CVE-2019-14857</a>

     <p>Insufficient validation of URLs leads to an Open Redirect
     vulnerability. An attacker may trick a victim into providing
     credentials for an OpenID provider by forwarding the request to an
     illegitimate website.</p></li>

<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-20479">CVE-2019-20479</a>

     <p>Due to insufficient validatation of URLs an Open Redirect
     vulnerability for URLs beginning with a slash and backslash could be
     abused.</p></li>

<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-1010247">CVE-2019-1010247</a>

     <p>The OIDCRedirectURI page contains generated JavaScript code that uses
     a poll parameter as a string variable, thus might contain additional
     JavaScript code. This might result in Criss-Site Scripting (XSS).</p>


<p>For Debian 9 stretch, these problems have been fixed in version
2.1.6-1+deb9u1.</p>

<p>We recommend that you upgrade your libapache2-mod-auth-openidc packages.</p>
