Created libvncserver tracking bugs for this issue: Affects: epel-7 [bug 1860355] Affects: fedora-all [bug 1860356] This bug seems to be much more a reliability issue than a security one. After speaking with upstream, I'm going to set this as not a security issue because there is no known path of exploitation or trust boundary crossing. Statement: This flaw does not affect versions of vino shipped with Red Hat Enterprise Linux 6, 7, or 8 because vino does not ship the libvncclient. Additionally, Red Hat Product Security does not consider this to be a security vulnerability because no trust boundary is crossed and there is no known path of exploitation. This is a standard software reliability bug. |
