In versions prior to 3.4.3, when using a daemon configured with a chroot, the reverse DNS lookup of the connecting client was performed after the chroot had been entered. If the chroot did not contain the files glibc needs for resolution (/etc/resolv.conf, /etc/nsswitch.conf,\n/etc/hosts, NSS service modules), the lookup failed and the connecting hostname was set to \"UNKNOWN\". Hostname-based deny rules (\"hosts deny = *.evil.example\") therefore could not match, and an attacker who controlled the PTR record for their source IP could connect from a hostname that the administrator had intended to deny. IP-based ACLs (\"hosts allow = 10.0.0.0/8\") are unaffected. This issue is fixed in version 3.4.3."}], "problemTypes": [{"descriptions": [{"lang": "en", "type": "CWE", "cweId": "CWE-863", "description": "CWE-863: Incorrect Authorization"}]}], "providerMetadata": {"orgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "shortName": "GitHub_M", "dateUpdated": "2026-07-20T20:29:26.577Z"}}, "adp": [{"providerMetadata": {"shortName": "CISA-ADP", "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "dateUpdated": "2026-07-21T12:50:47.912Z"}, "title": "CISA ADP Vulnrichment"}]}, "cveMetadata": {"cveId": "CVE-2026-44507", "state": "PUBLISHED", "dateUpdated": "2026-07-20T20:29:26.577Z", "dateReserved": "2026-05-06T18:28:20.886Z", "assignerOrgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "datePublished": "2026-07-20T20:29:26.577Z", "assignerShortName": "GitHub_M"}, "dataVersion": "5.2"}
