Comment 1 Marian Rehak 2020-07-24 10:33:14 UTC 
Created libvncserver tracking bugs for this issue:

Affects: epel-7 [bug 1860341]
Affects: fedora-all [bug 1860342]
Comment 2 Todd Cullum 2020-07-27 22:32:57 UTC 
Statement:

versions of libvncserver and vino that ship with Red Hat Enterprise Linux 6 through 8 (inclusive) are not affected because the vulnerable code was introduced in a later version.
