Package : shibboleth-sp2
Version : 2.4.3+dfsg-5+deb7u2
CVE ID : CVE-2017-16852
Debian Bug : 881857

Rod Widdowson of Steading System Software LLP discovered a coding error
in the "Dynamic" metadata plugin of the Shibboleth Service Provider,
causing the plugin to fail configuring itself with the filters provided
and omitting whatever checks they are intended to perform.

For Debian 7 "Wheezy", these problems have been fixed in version
2.4.3+dfsg-5+deb7u2.

We recommend that you upgrade your shibboleth-sp2 packages.
