Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.","published":"2017-06-19T16:29:00.000Z","lastModified":"2026-06-17T00:59:02.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-119"],"affected":["redhat/enterprise linux","redhat/enterprise linux desktop","redhat/enterprise linux server","redhat/enterprise linux server aus","redhat/enterprise linux server eus","redhat/enterprise linux server long life","redhat/enterprise linux server tus","redhat/enterprise linux workstation","openstack/cloud magnum orchestration","novell/suse linux enterprise desktop","novell/suse linux enterprise point of sale","novell/suse linux enterprise server","opensuse/leap","suse/linux enterprise for sap","suse/linux enterprise server","suse/linux enterprise server for raspberry pi","suse/linux enterprise software development kit","gnu/glibc","debian/debian linux","mcafee/web gateway"],"epss":{"score":0.02733,"percentile":0.86023,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":3,"verified":true,"firstPublished":"2017-06-28","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":42276,"kind":"exploit","title":"Linux Kernel (Debian 9/10 / Ubuntu 14.04.5/16.04.2/17.04 / Fedora 23/24/25) - 'ldso_dynamic Stack Clash' Local Privilege Escalation","url":"https://www.exploit-db.com/exploits/42276","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux_x86/local/42276.c","file":"exploits/linux_x86/local/42276.c","published":"2017-06-28","added":"2017-06-28","updated":"2017-07-19","author":"Qualys Corporation","type":"local","platform":"linux_x86","port":null,"verified":true,"codes":["CVE-2017-1000371","CVE-2017-1000366"],"tags":null,"aliases":"Stack Clash","applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://www.qualys.com/2017/06/19/stack-clash/linux_ldso_dynamic.c"},{"edbId":42275,"kind":"exploit","title":"Linux Kernel (Debian 7.7/8.5/9.0 / Ubuntu 14.04.2/16.04.2/17.04 / Fedora 22/25 / CentOS 7.3.1611) - 'ldso_hwcap_64 Stack Clash' Local Privilege Escalation","url":"https://www.exploit-db.com/exploits/42275","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux_x86-64/local/42275.c","file":"exploits/linux_x86-64/local/42275.c","published":"2017-06-28","added":"2017-06-28","updated":"2017-07-19","author":"Qualys Corporation","type":"local","platform":"linux_x86-64","port":null,"verified":true,"codes":["CVE-2017-1000379","CVE-2017-1000366"],"tags":null,"aliases":"Stack Clash","applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://www.qualys.com/2017/06/19/stack-clash/linux_ldso_hwcap_64.c"},{"edbId":42274,"kind":"exploit","title":"Linux Kernel (Debian 7/8/9/10 / Fedora 23/24/25 / CentOS 5.3/5.11/6.0/6.8/7.2.1511) - 'ldso_hwcap Stack Clash' Local Privilege Escalation","url":"https://www.exploit-db.com/exploits/42274","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux_x86/local/42274.c","file":"exploits/linux_x86/local/42274.c","published":"2017-06-28","added":"2017-06-28","updated":"2017-07-19","author":"Qualys Corporation","type":"local","platform":"linux_x86","port":null,"verified":true,"codes":["CVE-2017-1000370","CVE-2017-1000366"],"tags":null,"aliases":"Stack Clash","applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://www.qualys.com/2017/06/19/stack-clash/linux_ldso_hwcap.c"}]},"verdict":{"level":"urgent","text":"3 public exploits are published in Exploit-DB (verified) and the impact is high, while EPSS rates exploitation at 2.7%.
