{"id":"DEBIAN-CVE-2026-57228","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.","modified":"2026-09-24T09:00:15.725970178Z","published":"2026-09-18T21:17:01.367Z","upstream":["CVE-2026-57228"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-57228"}],"affected":[{"package":{"name":"suricata","ecosystem":"Debian:13","purl":"pkg:deb/debian/suricata?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:7.0.10-1","1:7.0.10-1+deb13u1","1:7.0.10-1+deb13u2","1:7.0.10-1+deb13u3","1:7.0.10-1+deb13u4","1:7.0.11-1","1:7.0.11-1~bpo13+1","1:8.0.0-1~exp1","1:8.0.0-1~exp2","1:8.0.0-1~exp4","1:8.0.0-1~exp5","1:8.0.1-1","1:8.0.1-2","1:8.0.1-3","1:8.0.1-3~bpo13+1","1:8.0.2-1","1:8.0.2-1~bpo13+1","1:8.0.3-1","1:8.0.3-1~bpo13+1","1:8.0.3-2~exp1","1:8.0.4-1","1:8.0.4-1~bpo13+1","1:8.0.5-1","1:8.0.5-1~bpo13+1","1:8.0.6-1","1:8.0.6-1~bpo13+1","1:8.0.7-1","1:8.0.7-1~bpo13+1","1:8.0.7-2~exp1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-57228.json"}},{"package":{"name":"suricata","ecosystem":"Debian:14","purl":"pkg:deb/debian/suricata?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.0.1-1"}]}],"versions":["1:7.0.10-1","1:7.0.11-1","1:7.0.11-1~bpo13+1","1:8.0.0-1~exp1","1:8.0.0-1~exp2","1:8.0.0-1~exp4","1:8.0.0-1~exp5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-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"}]}
