{"id":"CVE-2016-3672","details":"The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits.","modified":"2026-03-20T11:09:22.713942Z","published":"2016-04-27T17:59:27.397Z","related":["MGASA-2016-0225","MGASA-2016-0233","SUSE-SU-2016:1690-1","SUSE-SU-2016:1937-1","SUSE-SU-2016:2105-1"],"references":[{"type":"WEB","url":"http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8b8addf891de8a00e4d39fc32f93f7c5eb8feceb"},{"type":"WEB","url":"http://hmarco.org/bugs/CVE-2016-3672-Unlimiting-the-stack-not-longer-dis"},{"type":"WEB","url":"http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182524.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/537996/100/0/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/bid/85884"},{"type":"WEB","url":"https://www.exploit-db.com/exploits/39669/"},{"type":"WEB","url":"http://seclists.org/fulldisclosure/2016/Apr/26"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00055.html"},{"type":"WEB","url":"http://hmarco.org/bugs/CVE-2016-3672-Unlimiting-the-stack-not-longer-disables-ASLR.html"},{"type":"WEB","url":"http://www.securitytracker.com/id/1035506"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2998-1"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2989-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2996-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3000-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3003-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3004-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2997-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3001-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3002-1"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0676"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html"},{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3607"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:1062"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1324749"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/8b8addf891de8a00e4d39fc32f93f7c5eb8feceb"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git","events":[{"introduced":"0"},{"fixed":"8b8addf891de8a00e4d39fc32f93f7c5eb8feceb"}]},{"type":"GIT","repo":"https://github.com/torvalds/linux","events":[{"introduced":"0"},{"fixed":"8b8addf891de8a00e4d39fc32f93f7c5eb8feceb"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git","events":[{"introduced":"0"},{"fixed":"8b8addf891de8a00e4d39fc32f93f7c5eb8feceb"}]},{"type":"GIT","repo":"https://github.com/torvalds/linux","events":[{"introduced":"0"},{"fixed":"8b8addf891de8a00e4d39fc32f93f7c5eb8feceb"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2016-3672.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"12.04"}]},{"events":[{"introduced":"0"},{"last_affected":"14.04"}]},{"events":[{"introduced":"0"},{"last_affected":"15.10"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0-sp1"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.5.2"}]},{"events":[{"introduced":"0"},{"last_affected":"4.5.2"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
