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":"2026-10-08T17:17:17.433+00:00","modifiedAt":"2026-10-08T21:35:53.89+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/commit/85a71bbe1faa36c552a960e6a5f3d0cfb632fbbe","https://github.com/moby/sys/pull/221","https://github.com/moby/sys/security/advisories/GHSA-mjcv-p78q-w5fw"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61801","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-400"],"productCriteria":[],"sourceDates":{"published":"2026-10-08T17:17:17.433","lastModified":"2026-10-08T21:35:53.890"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
