{"id":"AZL-98234","summary":"CVE-2026-18743 affecting package popt for versions less than 1.19-2","details":"A flaw was found in popt. This vulnerability allows an attacker to provide specially crafted configuration content to a host, which, when loaded, can lead to a small memory corruption issue. This occurs because of an error in how the `poptConfigFileToString` function reallocates memory for buffers. Successful exploitation could result in heap metadata corruption, potentially causing the affected process to become unavailable (denial of service).","modified":"2026-11-09T05:30:15Z","published":"2026-09-01T02:16:57Z","upstream":["CVE-2026-18743"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18743"}],"affected":[{"package":{"name":"popt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/popt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.19-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-98234.json"}}],"schema_version":"1.9.2"}
