Affects: fedora-all [bug 1735654]
Red Hat OpenStack Platform:
* This flaw impacts KVM user-mode or SLIRP networking, which is not used in Red Hat OpenStack Platform. Although updating is recommended for affected versions (see below), Red Hat OpenStack Platform environments are not vulnerable.
* Because the flaw's impact is Low, it will not be fixed in Red Hat OpenStack Platform 9 which is retiring within a few weeks of the flaw's public date.
There is no external mitigation to prevent this out-of-bounds heap memory access.
