CVE-2024-49769 (GCVE-0-2024-49769)

Vulnerability from cvelistv5 – Published: 2024-10-29 14:18 – Updated: 2024-11-17 00:11

Title

Waitress has a denial of service leading to high CPU usage/resource exhaustion

Summary

Waitress is a Web Server Gateway Interface server for Python 2 and 3. 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. Waitress 3.0.1 contains fixes that remove the race condition.

Severity
