Comment 1 Martin Prpič 2015-10-23 03:18:21 EDT

This issue did not affect the versions of ntp as shipped with Red Hat Enterprise Linux 5, 6, and 7. This issue only affected OpenVMS operating systems, which use characters other than "/" and "\" for directory separation, allowing exploitation of this flaw.
