"Luis Merino, Markus Vervier and Eric Sesterhenn discovered that
missing input sanitising in the Hylafax fax software could potentially
result in the execution of arbitrary code via a malformed fax message.

For Debian 8 'Jessie', this problem has been fixed in version
3:6.0.6-6+deb8u1.

We recommend that you upgrade your hylafax packages.

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