Created systemd tracking bugs for this issue:

Affects: fedora-all [bug 1284825]

Comment 6 Cedric Buissart 2016-01-13 09:37:40 UTC
The bug was introduced with the _nss_mymachines_getpwnam_r() & _nss_mymachines_getgrnam_r() functions, in v223.
RHEL7 is currently shipping older versions, and thus is not vulnerable.

Statement:

This issue did not affect the versions of systemd as shipped with Red Hat Enterprise Linux 7.
