Package        : opensaml2
CVE ID         : CVE-2017-16853
Debian Bug     : 881856

Rod Widdowson of Steading System Software LLP discovered a coding error
in the OpenSAML library, causing the DynamicMetadataProvider class to
fail configuring itself with the filters provided and omitting whatever
checks they are intended to perform.

For the oldstable distribution (jessie), this problem has been fixed
in version 2.5.3-2+deb8u2.

For the stable distribution (stretch), this problem has been fixed in
version 2.6.0-4+deb9u1.

We recommend that you upgrade your opensaml2 packages.
