header length and number of channels for PARIS Audio Format (PAF)
audio files. An attacker could exploit this to cause a denial of
service via application crash, or possibly execute arbitrary code with
the privileges of the user invoking the program.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
