Debian 10: DLA-3430-1 Moderate: Cups-Filters Command Execution

It was discovered that missing input sanitising in cups-filters, when
using the Backend Error Handler (beh) backend to create an accessible
network printer, may result in the execution of arbitrary commands.


For Debian 10 buster, this problem has been fixed in version
1.21.6-5+deb10u1.

We recommend that you upgrade your cups-filters packages.
