CVE-2024-49769 - Waitress DoS Lockup Vulnerability

CVE ID : CVE-2024-49769
Published : Oct. 29, 2024, 3:15 p.m. | 24 minutes ago
Description : 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: 7.5 | HIGH
