This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2017-1000111" }, { "type": "WEB", "url": "https://access.redhat.com/errata/RHSA-2017:2918" }, { "type": "WEB", "url": "https://access.redhat.com/errata/RHSA-2017:2930" }, { "type": "WEB", "url": "https://access.redhat.com/errata/RHSA-2017:2931" }, { "type": "WEB", "url": "https://access.redhat.com/errata/RHSA-2017:3200" }, { "type": "WEB", "url": "https://access.redhat.com/security/cve/cve-2017-1000111" }, { "type": "WEB", "url": "http://www.debian.org/security/2017/dsa-3981" }, { "type": "WEB", "url": "http://www.securityfocus.com/bid/100267" }, { "type": "WEB", "url": "http://www.securitytracker.com/id/1039132" } ], "database_specific": { "cwe_ids": [ "CWE-787" ], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2017-10-05T01:29:00Z" } }
