Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
8.7 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N

Summary

Waitress vulnerable to DoS leading to high CPU usage/resource exhaustion

Details

Impact

When a remote client closes the connection before waitress has had the opportunity to call getpeername() waitress won't correctly clean up the connection leading to the main thread attempting to write to a socket that no longer exists, but not removing it from the list of sockets to attempt to process. This leads to a busy-loop calling the write function.

A remote attacker could run waitress out of available sockets with very little resources required.

Patches

Waitress 3.0.1 contains fixes that remove the race condition.

Workarounds

No work-around.
