Access rights of Xenstore nodes are per domid. Unfortunately, existing granted access rights are not removed when a domain is being destroyed. This means that a new domain created with the same domid will inherit the access rights to Xenstore nodes from the previous domain(s) with the same domid. Because all Xenstore entries of a guest below /local/domain/ are being deleted by Xen tools when a guest is destroyed, only Xenstore entries of other guests still running are affected. For example, a newly created guest domain might be able to read sensitive information that had belonged to a previously existing guest domain. Both Xenstore implementations (C and Ocaml) are vulnerable.", "severity": [], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2020-29481" }, { "type": "WEB", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/2C6M6S3CIMEBACH6O7V4H2VDANMO6TVA" }, { "type": "WEB", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/OBLV6L6Q24PPQ2CRFXDX4Q76KU776GKI" }, { "type": "WEB", "url": "https://www.debian.org/security/2020/dsa-4812" }, { "type": "WEB", "url": "https://xenbits.xenproject.org/xsa/advisory-322.html" }, { "type": "WEB", "url": "http://www.openwall.com/lists/oss-security/2020/12/16/3" } ], "database_specific": { "cwe_ids": [ "CWE-668" ], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2020-12-15T18:15:00Z" } }
