{"id":"CVE-2019-13132","details":"In ZeroMQ libzmq before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.3.2, a remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations.","modified":"2026-05-15T12:03:34.226284189Z","published":"2019-07-10T19:15:10.517Z","related":["SUSE-FU-2022:0444-1","SUSE-FU-2022:0445-1","SUSE-SU-2019:14117-1","SUSE-SU-2019:1776-1","SUSE-SU-2019:1785-1","openSUSE-SU-2019:1767-1","openSUSE-SU-2024:11540-1"],"database_specific":{"unresolved_ranges":[{"vendor_product":"canonical:ubuntu_linux","cpes":["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:*:*:*:*:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:19.04:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"16.04"},{"last_affected":"18.04"},{"last_affected":"18.10"},{"last_affected":"19.04"}],"source":"CPE_FIELD"},{"vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"8.0"},{"last_affected":"9.0"}],"source":"CPE_FIELD"},{"cpes":["cpe:2.3:o:fedoraproject:fedora:29:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*"],"vendor_product":"fedoraproject:fedora","extracted_events":[{"last_affected":"29"},{"last_affected":"30"},{"last_affected":"31"}],"source":"CPE_FIELD"}]},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00033.html"},{"type":"WEB","url":"https://fangpenlin.com/posts/2024/04/07/how-i-discovered-a-9-point-8-critical-security-vulnerability-in-zeromq-with-mostly-pure-luck/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AVCTNUEOFFZUNJOXFCYCF3C6Y6NDILI3/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MK7SJYDJ7MMRRRPCUN3SCSE7YK6ZSHVS/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/T6HINI24SL7CU6XIJWUOSGTZWEFOOL7X/"},{"type":"WEB","url":"https://news.ycombinator.com/item?id=39970716"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/07/08/6"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/109284"},{"type":"ADVISORY","url":"https://github.com/zeromq/libzmq/issues/3558"},{"type":"ADVISORY","url":"https://github.com/zeromq/libzmq/releases"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/07/msg00007.html"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Jul/13"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201908-17"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4050-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4477"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
