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."}],"source":{"advisory":"GHSA-3f84-rpwh-47g6","discovery":"UNKNOWN"}},"adp":[{"affected":[{"vendor":"pylons","product":"waitress","cpes":["cpe:2.3:a:pylons:waitress:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThan":"3.0.1","versionType":"custom"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-29T14:56:24.506825Z","id":"CVE-2024-49769","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-29T14:56:55.296Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2024/11/msg00012.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-11-17T00:11:26.954Z"}}]}}
