"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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
