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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-732"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00028.html","http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00059.html","http://www.openwall.com/lists/oss-security/2019/05/16/1","http://www.securityfocus.com/bid/108360","https://github.com/sylabs/singularity/releases/tag/v3.2.0"],"products":["fedoraproject:fedora","opensuse:backports","opensuse:leap","sylabs:singularity"],"source":"nvd","synced_at":"2026-10-19T20:56:19.218283075+00:00"},"epss":{"cve":"CVE-2019-11328","score":0.02088,"percentile":0.81598,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-557g-r22w-9wvx","url":"https://osv.dev/vulnerability/GHSA-557g-r22w-9wvx","summary":"Incorrect Permission Assignment for Critical Resource in Singularity","modified":"2023-11-08T04:01:01.092123Z","packages":[{"ecosystem":"Go","name":"github.com/sylabs/singularity","purl":"pkg:golang/github.com/sylabs/singularity","ranges":[">=3.1.0 <3.2.0"],"fixed":["3.2.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
