The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host.","published":"2019-05-14T21:29:01.137Z","modified":"2026-10-24T10:50:34.191492499Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.02127,"percentile":0.80274,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Go","name":"github.com/sylabs/singularity","fixedVersion":"3.2.0"}],"fix":{"url":"https://github.com/sylabs/singularity/commit/618c9d56802399adb329c23ea2b70598eaff4a31","label":"sylabs/singularity@618c9d5"},"references":[{"type":"WEB","url":"http://www.securityfocus.com/bid/108360"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5O3TPL5OOTIZEI4H6IQBCCISBARJ6WL3/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LIHV7DSEVTB5SUPEZ2UXGS3Q6WMEQSO2/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LNU5BUHFOTYUZVHFUSX2VG4S3RCPUEMA/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00028.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00059.html"},{"type":"ADVISORY","url":"https://github.com/sylabs/singularity/releases/tag/v3.2.0"},{"type":"EVIDENCE","url":"http://www.openwall.com/lists/oss-security/2019/05/16/1"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-11328"},{"type":"WEB","url":"https://github.com/sylabs/singularity/commit/618c9d56802399adb329c23ea2b70598eaff4a31"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5O3TPL5OOTIZEI4H6IQBCCISBARJ6WL3"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LIHV7DSEVTB5SUPEZ2UXGS3Q6WMEQSO2"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LNU5BUHFOTYUZVHFUSX2VG4S3RCPUEMA"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-24T10:50:34.191492499Z"}}
