{"id":"GHSA-557g-r22w-9wvx","summary":"Incorrect Permission Assignment for Critical Resource in Singularity","details":"An issue was discovered in Singularity 3.1.0 to 3.2.0-rc2, a malicious user with local/network access to the host system (e.g. ssh) could exploit this vulnerability due to insecure permissions allowing a user to edit files within `/run/singularity/instances/sing/\u003cuser\u003e/\u003cinstance\u003e`. 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.","aliases":["CVE-2019-11328"],"modified":"2023-11-01T04:50:15.313526Z","published":"2021-12-20T18:25:33Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2021-05-17T15:50:05Z","nvd_published_at":"2019-05-14T21:29:00Z","cwe_ids":["CWE-269","CWE-732"],"severity":"HIGH"},"references":[{"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://github.com/sylabs/singularity/releases/tag/v3.2.0"},{"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"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00028.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00059.html"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2019/05/16/1"},{"type":"WEB","url":"http://www.securityfocus.com/bid/108360"}],"affected":[{"package":{"name":"github.com/sylabs/singularity","ecosystem":"Go","purl":"pkg:golang/github.com/sylabs/singularity"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.1.0"},{"fixed":"3.2.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/12/GHSA-557g-r22w-9wvx/GHSA-557g-r22w-9wvx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
