This message is a reminder that Fedora Linux 37 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 37 on 2023-12-05.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '37'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 37 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

The bundled libtiff in iv is very old. We, neuro-sig, looked into the code and concluded that the CVEs filed against iv regarding libtiff are either not applicable or, if they are, do not pose a high risk due to the nature of the iv package and its intended audience. IV, the InterViews graphical library, is consumed only by NEURON, a neuroscience application for modelling neurons and networks thereof.

Therefore, we decided in our meeting on 4 December 2023 [1] not to pursue this further.
