{"id":"AZL-44838","summary":"CVE-2021-20206 affecting package buildah for versions less than 1.41.4-2","details":"An improper limitation of path name flaw was found in containernetworking/cni in versions before 0.8.1. When specifying the plugin to load in the 'type' field in the network configuration, it is possible to use special elements such as \"../\" separators to reference binaries elsewhere on the system. This flaw allows an attacker to execute other existing binaries other than the cni plugins/types, such as 'reboot'. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.","modified":"2026-04-01T05:16:45.368949Z","published":"2021-03-26T22:15:12Z","upstream":["CVE-2021-20206"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-20206"}],"affected":[{"package":{"name":"buildah","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/buildah"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.41.4-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-44838.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
