The server bounds the mail it generates in response to a message - a rule forward, reply or copy, an account forward, a Sieve redirect, vacation or notify, a bounce, an out-of-office reply - by a counter it carries in the message's X-hMailServer-LoopCount header, and makes no more once the counter reaches the configured rule loop limit (5 by default); that is what ends a forwarding or auto-reply cycle in a bounded number of hops. X-hMailServer-LoopCount is an ordinary header that is not stripped from mail arriving from outside, and the server read it with a signed conversion and no validation, so a count below zero passed every test against the limit: a sender who sets X-hMailServer-LoopCount to a negative value, or on the Linux builds to a value above the 32-bit signed range that the conversion wraps to a negative one, lifts the bound, and a message that enters a generated-mail cycle then loops up to about two thousand million times, each hop a queued message and a delivery, filling the queue and disk and stopping mail service. The Sieve notify action (from 6.2.22) consulted no limit at all, and its increment of the count could overflow a signed integer; and an account could reset the counter on its own mail through a Sieve editheader of the header (from 6.2.22) or a rule Set header value action (all versions) ahead of a forward or redirect.\nhttps://www.cve.org/CVERecord?id=CVE-2026-107569https://gitlab.com/hmailserver/hmailserver/-/work_items/81https://gitlab.com/hmailserver/hmailserver/-/releases/v6.3.7#ProgressiveRobotLtd #hMailServer#CVE_2026_107569#bot", "url": "https://infosec.exchange/users/cve/statuses/117468357733981923"}, {"timestamp": "2026-10-19T16:17:01Z", "date_only": false, "value": "2026-10-19T16:17:01Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-95HV-G278-W9P8", "record": "GHSA-95HV-G278-W9P8", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-19T16:17:01.830Z", "date_only": false, "value": "2026-10-19T16:17:01.830", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-107569", "record": "FKIE_CVE-2026-107569", "field": "published"}, {"timestamp": "2026-10-19T18:32:11Z", "date_only": false, "value": "2026-10-19T18:32:11Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-95HV-G278-W9P8", "record": "GHSA-95HV-G278-W9P8", "field": "published"}, {"timestamp": "2026-10-19T18:32:11Z", "date_only": false, "value": "2026-10-19T18:32:11Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-95HV-G278-W9P8", "record": "GHSA-95HV-G278-W9P8", "field": "modified"}, {"timestamp": "2026-10-20T19:27:14.386Z", "date_only": false, "value": "2026-10-20T19:27:14.386515Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "cve-2026-107569", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-20T19:27:14.386Z", "date_only": false, "value": "2026-10-20T19:27:14.386515Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-107569", "record": "FKIE_CVE-2026-107569", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-20T19:27:26.604Z", "date_only": false, "value": "2026-10-20T19:27:26.604Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "cve-2026-107569", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-20T19:27:26.604Z", "date_only": false, "value": "2026-10-20T19:27:26.604Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "cve-2026-107569", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-20T20:17:13.973Z", "date_only": false, "value": "2026-10-20T20:17:13.973", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-107569", "record": "FKIE_CVE-2026-107569", "field": "lastModified"}]}
