A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2020-10702" }, { "type": "WEB", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10702" }, { "type": "WEB", "url": "https://git.qemu.org/?p=qemu.git;a=commit;h=de0b1bae6461f67243282555475f88b2384a1eb9" }, { "type": "WEB", "url": "https://security.netapp.com/advisory/ntap-20200724-0007" } ], "database_specific": { "cwe_ids": [], "severity": "LOW", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2020-06-04T18:15:00Z" } }
