## Packages

* [libppd](https://ubuntu.com/security/cves?package=libppd) - OpenPrinting libppd

## Details

It was discovered that libppd incorrectly parsed certain Postscript
objects. If a user or automated system were tricked into printing a
specially crafted document, a remote attacker could use this issue to cause
libppd to crash, resulting in a denial of service, or possibly execute
arbitrary code.

## Update instructions

In general, a standard system update will make all the necessary changes.
