{"id":"CVE-2018-16890","details":"libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.","aliases":["CURL-CVE-2018-16890"],"modified":"2026-09-10T03:45:21.930311906Z","published":"2019-02-06T20:29:00.243Z","related":["SUSE-SU-2019:0248-1","SUSE-SU-2019:0249-1","SUSE-SU-2019:0249-2","SUSE-SU-2019:0339-1","openSUSE-SU-2019:0174-1","openSUSE-SU-2024:10582-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:a:f5:big-ip_access_policy_manager:*:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"13.1.0"},{"last_affected":"13.1.3"},{"introduced":"14.0.0"},{"last_affected":"14.1.2"},{"introduced":"15.0.0"},{"last_affected":"15.0.1"}],"source":"CPE_RANGE","vendor_product":"f5:big-ip_access_policy_manager"},{"source":"CPE_RANGE","vendor_product":"siemens:sinema_remote_connect_client","cpes":["cpe:2.3:a:siemens:sinema_remote_connect_client:*:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"2.0"}]},{"extracted_events":[{"introduced":"14.04"},{"last_affected":"14.04"},{"introduced":"16.04"},{"last_affected":"16.04"},{"introduced":"18.04"},{"last_affected":"18.04"},{"introduced":"18.10"},{"last_affected":"18.10"}],"source":"CPE_STRING","vendor_product":"canonical:ubuntu_linux","cpes":["cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.10:*:*:*:*:*:*:*"]},{"vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"}],"source":"CPE_STRING"},{"cpes":["cpe:2.3:a:oracle:communications_operations_monitor:3.4:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_operations_monitor:4.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"3.4"},{"last_affected":"3.4"},{"introduced":"4.0"},{"last_affected":"4.0"}],"source":"CPE_STRING","vendor_product":"oracle:communications_operations_monitor"},{"cpes":["cpe:2.3:a:oracle:http_server:12.2.1.3.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"12.2.1.3.0"},{"last_affected":"12.2.1.3.0"}],"source":"CPE_STRING","vendor_product":"oracle:http_server"},{"source":"CPE_STRING","vendor_product":"oracle:secure_global_desktop","cpes":["cpe:2.3:a:oracle:secure_global_desktop:5.4:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"5.4"},{"last_affected":"5.4"}]},{"vendor_product":"redhat:enterprise_linux","cpes":["cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"8.0"},{"last_affected":"8.0"}],"source":"CPE_STRING"}]},"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/8338a0f605bdbb3a6098bb76f666a95fc2b2f53f37fa1ecc89f1146f%40%3Cdevnull.infra.apache.org%3E"},{"type":"WEB","url":"https://support.f5.com/csp/article/K03314397?utm_source=f5support&amp%3Butm_medium=RSS"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106947"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:3701"},{"type":"ADVISORY","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-436177.pdf"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3882-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4386"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16890"},{"type":"FIX","url":"https://curl.haxx.se/docs/CVE-2018-16890.html"},{"type":"FIX","url":"https://security.netapp.com/advisory/ntap-20190315-0001/"},{"type":"FIX","url":"https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html"},{"type":"FIX","url":"https://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/curl/curl","events":[{"introduced":"4f041c9d6e61829310eb0715d8edb2a232478123"},{"fixed":"55d1974913cae8b5ee6d01667a282531ff17d096"}],"database_specific":{"cpe":"cpe:2.3:a:haxx:libcurl:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"7.36.0"},{"fixed":"7.64.0"}],"source":"CPE_RANGE"}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-16890.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
