nmap version 7.80 crashes on Ubuntu 20.04 LTS:
$ sudo nmap -n 192.168.1.223/24
Starting Nmap 7.80 ( https://nmap.org ) at 2020-12-15 09:18 CET
nmap: Target.cc:503: void Target::stopTimeOutClock(const timeval*): Assertion `htn.toclock_running
== true' failed.
Aborted
Issue was reported in nmap github repository:
- https://github.com/nmap/nmap/issues/1797
- https://github.com/nmap/nmap/issues/1764
Issue is fixed since nmap 7.90 by following commit:
- https://github.com/nmap/nmap/commit/33f421fd6e68fcb8ed50071661d9704717c81b2b
Please integrate aboce change into nmap releaseon Ubuntu 20.04 LTS or upgrade nmap to newer version |
[Impact]
Within affected networks, nmap can intermittently hit an assertion involving a timeout clock.
[Test Case]
This bug presents itself under certain network conditions we've not isolated, making reproduction of the issue challenging. Even for those who experience the issue, it can only appear once in scores or hundreds of runs. For this reason, we're relying on community members to handle the validation requirements by confirming the absence of the abnormal termination in their own environments after running it for a period of days or weeks.
A suggested workload to help trigger the crash is to run nmap in a loop against a subnet IP known to crash, e.g.:
c=0
while sudo nmap -PS22 -p22 192.168.77.0/24
do c=$(($c+1))
echo $c
done
So, the plan for testing this bug will involve asking these kind community members to install the package from -proposed and run it continuously for some time. The expectation is that the assertion will not manifest with the new package.
[Where Problems Could Occur]
The fix involves a modification to stop the timeout clock, which is intended to happen when an unexpected ARP response is received. Thus, issues to watch for would be odd behaviors relating to unsolicited ARP responses, new assertions or crashes occurring elsewhere in the program, and program timeouts that occur when they shouldn't or don't occur when they should.
