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.

7.0.17.","dates":{"published":"2026-09-18T20:11:24.343Z","modified":"2026-09-21T20:47:40.290Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.1,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.2,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
