Description Hank Leininger 2023-11-29 22:17:12 UTC

Upstream acknowledged this and patched 2023-07-20 but there's no new release yet.

nmap-4.94 included a reworking of some list loading/processing, and in the process introduced a bug where nmap --top-ports with an argument larger than 4260 causes a segfault.

Fix in https://github.com/nmap/nmap/commit/edad9c059ca45bccab8c0f41fe6fc6546c60153a

I'll submit a PR shortly.

Your version here is wrong.
nmap-4.94 --> nmap-7.94

Haha whoops you are right, fixed the typo in the Summary, thanks. Can't edit my comment, though.
