This issue, referred to as the \"MadeYouReset\" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS)."}], "lastModified": "2025-09-02T15:55:25.420", "sourceIdentifier": "secalert@redhat.com"}
