{"id":"AZL-81911","summary":"CVE-2026-3184 affecting package util-linux for versions less than 2.40.2-4","details":"A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.","modified":"2026-09-02T06:51:55Z","published":"2026-04-03T19:17:23Z","upstream":["CVE-2026-3184"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-3184"}],"affected":[{"package":{"name":"util-linux","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/util-linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.40.2-4"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-81911.json"}}],"schema_version":"1.9.0"}
