Description

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.

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.
