{"id":"UBUNTU-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":"2026-04-22T13:31:33.333822Z","published":"2019-07-08T16:00:00Z","related":["USN-4050-1","USN-4920-1"],"upstream":["CVE-2019-13132"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-13132"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4050-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-13132"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4920-1"}],"affected":[{"package":{"name":"zeromq3","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/zeromq3@4.0.4+dfsg-2ubuntu0.1+esm1?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.0.4+dfsg-2ubuntu0.1+esm1"}]}],"versions":["3.2.3+dfsg-2","3.2.4+dfsg-1","3.2.4+dfsg-2","3.2.4+dfsg-3","3.2.4+dfsg-4","4.0.3+dfsg-1","4.0.4+dfsg-2","4.0.4+dfsg-2ubuntu0.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro","binaries":[{"binary_name":"libzmq3","binary_version":"4.0.4+dfsg-2ubuntu0.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13132.json"}},{"package":{"name":"zeromq3","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/zeromq3@4.1.4-7ubuntu0.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.1.4-7ubuntu0.1"}]}],"versions":["4.0.5+dfsg-3ubuntu1~gcc5.1","4.0.5+dfsg-3ubuntu2","4.1.4-7"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libzmq5","binary_version":"4.1.4-7ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13132.json"}},{"package":{"name":"zeromq3","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/zeromq3@4.2.5-1ubuntu0.2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.5-1ubuntu0.2"}]}],"versions":["4.2.1-4ubuntu1","4.2.2-1ubuntu2","4.2.3-1","4.2.3-1build1","4.2.5-1","4.2.5-1ubuntu0.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"4.2.5-1ubuntu0.2","binary_name":"libzmq5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13132.json"}}],"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"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"high"}]}
