Created samba tracking bugs for this issue: Affects: fedora-all [bug 1405984] External Reference: https://www.samba.org/samba/security/CVE-2016-2126.html No mitigation exists for this issue. However, using "machine password timeout = 0" will prevent the bug from being triggered accidentally when the machine password is changed. I am unable to access any of the related bugs for this to see what is going on. Can someone working this issue post a status update as to having an errata opened for RHEL here?
