{"id":"AZL-10819","summary":"CVE-2022-1271 affecting package gzip for versions less than 1.12-1","details":"An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.","modified":"2026-04-01T05:06:26.500747Z","published":"2022-08-31T16:15:09Z","upstream":["CVE-2022-1271"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-1271"}],"affected":[{"package":{"name":"gzip","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/gzip"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.12-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-10819.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
