minissdpd, a network device discovery daemon. A remote attacker could
abuse this to crash the process.

For Debian 8 'Jessie', this issue has been fixed in minissdpd version
1.2.20130907-3+deb8u2.

We recommend that you upgrade your minissdpd packages.

to automatically clean and format it as much as possible without
introducing additional issues."
