Comment 1 Guilherme de Almeida Suckevicz 2021-09-13 18:41:43 UTC
Created mingw-libtiff tracking bugs for this issue:

Affects: fedora-all [bug 2003802]

Comment 2 Garrett Tucker 2021-09-15 17:30:28 UTC
No RHEL Affects. The affected version was never introduced into a RHEL Stream and as such we are not affected by this flaw.

Comment 3 juneau 2021-09-21 13:47:35 UTC
No hosted services affects if flaw is limited to 4.0.10 as that version is not present.

Comment 4 Product Security DevOps Team 2021-09-21 18:21:27 UTC
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):
