This occurs because '\\0' characters are mishandled, and can lead to out-of-bounds writes and remote code execution.","modified":"2026-04-16T04:33:02.148420987Z","published":"2019-08-29T14:15:11.037Z","related":["SUSE-SU-2019:2454-1","SUSE-SU-2019:2514-1","openSUSE-SU-2019:2278-1","openSUSE-SU-2019:2281-1","openSUSE-SU-2024:10726-1","openSUSE-SU-2025:14715-1"],"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00024.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KVHY3MU2OK2EWZJFGNDSAOMD42L7DFPX/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YSJVVVRAE3SITC2ZLGCPMFDN3WVYZBWF/"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00026.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3GYTZLLDNIFWT7D7JSB25ERJNMOR4CQ3/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2822"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/08/msg00035.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2836"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:2885"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201908-29"},{"type":"ADVISORY","url":"https://www.dovecot.org/security.html"},{"type":"FIX","url":"https://dovecot.org/pipermail/dovecot-news/2019-August/000417.html"},{"type":"EVIDENCE","url":"http://www.openwall.com/lists/oss-security/2019/08/28/3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dovecot/core","events":[{"introduced":"0"},{"fixed":"baf9232c12705b02bcfc12493f61e0f2d23612a0"},{"introduced":"c8b89eb9968980589904a58e8bd72fc8c00039be"},{"fixed":"3c910f64bf3bd57cdf2703cf4c36c7613f1107f0"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2.2.36.4"},{"introduced":"2.3.0"},{"fixed":"2.3.7.2"}]}},{"type":"GIT","repo":"https://github.com/dovecot/pigeonhole","events":[{"introduced":"0"},{"fixed":"7372921a72f6a01ac0708aa58827b3f935d45d39"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"0.5.7.2"}]}}],"versions":["0.1.0","0.1.1","0.1.2","0.1.3","0.1.4","0.2.0","0.2.1","0.2.2","0.2.3","0.2.4","0.2.5","0.4.0","0.4.1","0.4.10","0.4.10.rc1","0.4.10.rc2","0.4.11","0.4.11.rc1","0.4.2","0.4.3","0.4.4","0.4.5","0.4.6","0.4.7","0.4.7.rc1","0.4.7.rc2","0.4.7.rc3","0.4.8","0.4.8.rc1","0.4.8.rc2","0.4.8.rc3","0.4.9","0.4.9.rc1","0.5.7","0.5.7.1","1.1.alpha1","1.1.alpha2","1.1.alpha4","1.1.alpha5","1.1.alpha6","1.1.beta1","1.1.beta10","1.1.beta11","1.1.beta12","1.1.beta13","1.1.beta14","1.1.beta16","1.1.beta2","1.1.beta3","1.1.beta4","1.1.beta5","1.1.beta6","1.1.beta8","1.1.beta9","1.1.rc1","1.1.rc2","1.1.rc3","1.2.alpha1","1.2.alpha2","1.2.alpha3","1.2.alpha4","1.2.alpha5","1.2.beta1","1.2.beta2","1.2.beta3","1.2.beta4","1.2.rc1","2.0.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.0.7","2.0.8","2.0.alpha1","2.0.alpha2","2.0.alpha3","2.0.beta1","2.0.beta2","2.0.beta3","2.0.beta4","2.0.beta5","2.0.beta6","2.0.rc1","2.0.rc2","2.0.rc3","2.0.rc4","2.0.rc5","2.0.rc6","2.1.alpha1","2.1.alpha2","2.1.beta1","2.1.rc1","2.1.rc2","2.1.rc3","2.1.rc4","2.1.rc5","2.1.rc6","2.2.0","2.2.1","2.2.10","2.2.11","2.2.12","2.2.13","2.2.13.rc1","2.2.14","2.2.14.rc1","2.2.15","2.2.16","2.2.16.rc1","2.2.17","2.2.17.rc1","2.2.17.rc2","2.2.18","2.2.19","2.2.19.rc1","2.2.19.rc2","2.2.2","2.2.20","2.2.20.rc1","2.2.3","2.2.36","2.2.36.1","2.2.36.3","2.2.36.rc1","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9","2.2.alpha1","2.2.beta1","2.2.beta2","2.2.rc1","2.2.rc2","2.2.rc3","2.2.rc4","2.2.rc5","2.2.rc6","2.2.rc7","2.3.7","2.3.7.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-11500.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"30"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
