Package : libapache2-mod-auth-openidc
Version : 1.6.0-1+deb8u2
CVE ID : CVE-2019-14857
Debian Bug : 942165

A security vulnerability was found in libapache2-mod-auth-openidc, the
OpenID Connect authentication module for the Apache HTTP server.

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.

For Debian 8 "Jessie", this problem has been fixed in version
1.6.0-1+deb8u2.

We recommend that you upgrade your libapache2-mod-auth-openidc packages.
