{"id":"CVE-2026-57228","summary":"Suricata smtp/mime: heap out-of-bounds read quoted-printable decoder","details":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 7.0.13 until 7.0.17, the SMTP MIME quoted-printable decoder in src/util-decode-mime.c can read one byte past a heap buffer when a quoted-printable escape sequence is split across traffic chunks and the following chunk contains exactly one byte. Crafted SMTP traffic can trigger the out-of-bounds read and crash Suricata when decode-quoted-printable MIME decoding is enabled. This issue is fixed in version 7.0.17.","aliases":["GHSA-qxm4-q7vx-7xj4"],"modified":"2026-09-19T11:45:30.416579242Z","published":"2026-09-18T20:11:24.343Z","related":["openSUSE-SU-2026:11308-1"],"database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57228.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57228.json"},{"type":"FIX","url":"https://github.com/OISF/suricata/commit/19880f9d5bbe2b8f8e8867a577848dce2b532c86"},{"type":"WEB","url":"https://github.com/OISF/suricata/releases/tag/suricata-7.0.17"},{"type":"ADVISORY","url":"https://github.com/OISF/suricata/security/advisories/GHSA-qxm4-q7vx-7xj4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57228"},{"type":"WEB","url":"https://redmine.openinfosecfoundation.org/issues/8608"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/oisf/suricata","events":[{"introduced":"090542709cf620f2053dc03b52ab8aa625dd6eff"},{"fixed":"f707f3208de8216e4eccada5c10e6edce460a82a"}],"database_specific":{"extracted_events":[{"introduced":"7.0.13"},{"fixed":"7.0.17"}],"source":"AFFECTED_FIELD"}}],"versions":["suricata-7.0.16","suricata-7.0.15","suricata-7.0.14","suricata-7.0.13"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57228.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:L/I:N/A:H"}]}
