Comment 1 Patrick Del Bello 2023-12-12 20:21:59 UTC 
Created ncurses tracking bugs for this issue:

Affects: fedora-all [bug 2254245]
Comment 3 Joe Orton 2023-12-13 13:00:22 UTC 
This looks like it can only be triggered via "tic", which is used to process terminfo from source to compiled form, and the input is trusted. The practical impact is very limited - it is similar to gcc crashing - why has this been assigned a CVE name at all?
