When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://www.openbsd.org/errata66.html"},{"url":"https://www.openwall.com/lists/oss-security/2019/12/11/9"},{"name":"20191212 Local Privilege Escalation in OpenBSD's dynamic loader (CVE-2019-19726)","tags":["mailing-list"],"url":"https://seclists.org/bugtraq/2019/Dec/25"},{"url":"http://packetstormsecurity.com/files/155658/Qualys-Security-Advisory-OpenBSD-Dynamic-Loader-Privilege-Escalation.html"},{"name":"20191213 Local Privilege Escalation in OpenBSD's dynamic loader (CVE-2019-19726)","tags":["mailing-list"],"url":"http://seclists.org/fulldisclosure/2019/Dec/31"},{"url":"http://packetstormsecurity.com/files/155764/OpenBSD-Dynamic-Loader-chpass-Privilege-Escalation.html"},{"name":"[oss-security] 20231003 CVE-2023-4911: Local Privilege Escalation in the glibc's ld.so","tags":["mailing-list"],"url":"http://www.openwall.com/lists/oss-security/2023/10/03/2"},{"name":"20231005 CVE-2023-4911: Local Privilege Escalation in the glibc's ld.so","tags":["mailing-list"],"url":"http://seclists.org/fulldisclosure/2023/Oct/11"},{"url":"http://packetstormsecurity.com/files/174986/glibc-ld.so-Local-Privilege-Escalation.html"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-05T02:25:12.567Z"},"title":"CVE Program Container","references":[{"url":"https://www.openbsd.org/errata66.html","tags":["x_transferred"]},{"url":"https://www.openwall.com/lists/oss-security/2019/12/11/9","tags":["x_transferred"]},{"name":"20191212 Local Privilege Escalation in OpenBSD's dynamic loader (CVE-2019-19726)","tags":["mailing-list","x_transferred"],"url":"https://seclists.org/bugtraq/2019/Dec/25"},{"url":"http://packetstormsecurity.com/files/155658/Qualys-Security-Advisory-OpenBSD-Dynamic-Loader-Privilege-Escalation.html","tags":["x_transferred"]},{"name":"20191213 Local Privilege Escalation in OpenBSD's dynamic loader (CVE-2019-19726)","tags":["mailing-list","x_transferred"],"url":"http://seclists.org/fulldisclosure/2019/Dec/31"},{"url":"http://packetstormsecurity.com/files/155764/OpenBSD-Dynamic-Loader-chpass-Privilege-Escalation.html","tags":["x_transferred"]},{"name":"[oss-security] 20231003 CVE-2023-4911: Local Privilege Escalation in the glibc's ld.so","tags":["mailing-list","x_transferred"],"url":"http://www.openwall.com/lists/oss-security/2023/10/03/2"},{"name":"20231005 CVE-2023-4911: Local Privilege Escalation in the glibc's ld.so","tags":["mailing-list","x_transferred"],"url":"http://seclists.org/fulldisclosure/2023/Oct/11"},{"url":"http://packetstormsecurity.com/files/174986/glibc-ld.so-Local-Privilege-Escalation.html","tags":["x_transferred"]}]}]}}
