memory corruption when processing malformed terminfo data entries
loaded by setuid/setgid programs

CVE-2023-29491.patch change the --disable-root-environ configure option
behavior.
set --disable-root-environ in configuration options.

--disable-root-environ option with a few additional changes
to the code allows us to mitigate CVE-2023-29491 and avoid
other issues that involve the possibility of malicious use of
environment variables through setuid applications, and, therefore,
it was the fix chosen in order to resolve this vulnerability.
