"Two input sanitization failures have been found in the faxrunq and
faxq binaries in mgetty. An attacker could leverage them to insert
commands via shell metacharacters in jobs id and have them executed
with the privilege of the faxrunq/faxq user.

For Debian 8 'Jessie', this problem has been fixed in version
1.1.36-2.1+deb8u1.

We recommend that you upgrade your mgetty 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."
