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" ] } ] } ] } }
