NVD Description

Note: Versions mentioned in the description apply only to the upstream mgetty package and not the mgetty package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

An issue was discovered in mgetty before 1.2.1. In fax/faxq-helper.c, the function do_activate() does not properly sanitize shell metacharacters to prevent command injection. It is possible to use the ||, &&, or > characters within a file created by the "faxq-helper activate <jobid>" command.
