Versions before 0.4.1 do not sufficiently limit entries when parsing `/etc/passwd`- or `/etc/group`-style files, allowing an attacker who can supply a specially crafted file to cause excessive memory consumption and potentially terminate the affected process due to an out-of-memory condition. This issue is patched in version 0.4.1. As a workaround, avoid parsing attacker-controlled user or group database files, or validate and limit untrusted input before parsing it.","state":0,"publishedAt":"2026-10-08T16:22:25.558+00:00","modifiedAt":"2026-10-08T17:27:37.645+00:00","affected":[{"ecosystem":"Vendor product","name":"sys","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"moby\",\n                    \"product\": \"sys\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.4.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5,"severity":"MEDIUM"}],"references":["https://github.com/moby/sys/security/advisories/GHSA-mjcv-p78q-w5fw","https://github.com/moby/sys/pull/221","https://github.com/moby/sys/commit/85a71bbe1faa36c552a960e6a5f3d0cfb632fbbe"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61801","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61801","identifiers":["CVE-2026-61801"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
