{"cve":"CVE-2017-1087","nvd":{"published":"2017-11-16T20:29:00.237","modified":"2026-06-17T01:13:52.850","status":"Modified","description":"In FreeBSD 10.x before 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24 named paths are globally scoped, meaning a process located in one jail can read and modify the content of POSIX shared memory objects created by a process in another jail or the host system. As a result, a malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. This memory region might be executed by applications trusting the shared memory, like Squid. This issue could lead to a Denial of Service or local privilege escalation.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-22"],"references":["http://www.securityfocus.com/bid/101867","http://www.securitytracker.com/id/1039810","https://www.freebsd.org/security/advisories/FreeBSD-SA-17:09.shm.asc","http://www.securityfocus.com/bid/101867","http://www.securitytracker.com/id/1039810"],"products":["freebsd:freebsd"],"source":"nvd","synced_at":"2026-10-19T20:47:01.408438353+00:00"},"epss":{"cve":"CVE-2017-1087","score":0.00415,"percentile":0.35827,"date":"2026-10-31"},"kev":null,"osv":[],"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).
