{"id":"AZL-94508","summary":"CVE-2026-18739 affecting package popt 1.19-1","details":"A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacker to execute arbitrary code if the host application then unsafely processes the altered data.","modified":"2026-08-30T05:26:50Z","published":"2026-08-04T06:16:30Z","upstream":["CVE-2026-18739"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18739"}],"affected":[{"package":{"name":"popt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/popt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.19-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-94508.json"}}],"schema_version":"1.9.0"}
