{"id":"CVE-2019-10053","details":"An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \\n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \\r results in an integer underflow.","modified":"2026-03-23T05:10:10.225040Z","published":"2019-05-13T21:29:01.560Z","related":["openSUSE-SU-2025:15394-1"],"references":[{"type":"ADVISORY","url":"https://lists.openinfosecfoundation.org/pipermail/oisf-announce/"},{"type":"FIX","url":"https://suricata-ids.org/2019/04/30/suricata-4-1-4-released/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/oisf/suricata","events":[{"introduced":"787473ec64550a2448b81aa13064c1f613642c57"},{"fixed":"14c2b6e445b3e8b5f802c4538397c12bfd3f831d"}],"database_specific":{"versions":[{"introduced":"4.1.0"},{"fixed":"4.1.4"}]}}],"versions":["suricata-4.1.0","suricata-4.1.1","suricata-4.1.2","suricata-4.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-10053.json"}}],"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"}]}
