Debian LTS: DLA-3904-1: cups Security Advisory Updates
Summary
Simone Margaritelli reported that cups, the Common UNIX Printing System,
does not properly sanitize IPP attributes when creating PPD files, which
may result in the execution of arbitrary code.
For Debian 11 bullseye, this problem has been fixed in version
2.3.3op2-3+deb11u9.
We recommend that you upgrade your cups packages.
