Bug#1043171: nmap: segfault when using service-names with -p

[Christopher Bock]

Package: nmap
Version: 7.94+dfsg1-3
Severity: normal

Hi,

when i try to use a service-name instead of the port-number nmap
breaks with a segfault.

cb@asterix ~ % nmap -p ssh localhost
Starting Nmap 7.94 ( https://nmap.org ) at 2023-08-06 22:51 CEST
[1] 806174 segmentation fault (core dumped) nmap -p ssh localhost
139 cb@asterix ~ %

I also tried other service-names and the really odd thing is that it
works occasionally but most of the time it doesn't.

As i don't really can make heads or tails from an strace i will leave
at that.

With many regards,
Christopher Bock
