{"id":"DEBIAN-CVE-2018-17974","details":"An issue was discovered in Tcpreplay 4.3.0 beta1. A heap-based buffer over-read was triggered in the function dlt_en10mb_encode() of the file plugins/dlt_en10mb/en10mb.c, due to inappropriate values in the function memmove(). The length (pktlen + ctx -\u003e l2len) can be larger than source value (packet + ctx-\u003el2len) because the function fails to ensure the length of a packet is valid. This leads to Denial of Service.","modified":"2026-09-01T16:04:40.401228810Z","published":"2018-10-03T22:29:00.907Z","upstream":["CVE-2018-17974"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-17974"}],"affected":[{"package":{"name":"tcpreplay","ecosystem":"Debian:12","purl":"pkg:deb/debian/tcpreplay?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2018-17974.json"}},{"package":{"name":"tcpreplay","ecosystem":"Debian:13","purl":"pkg:deb/debian/tcpreplay?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2018-17974.json"}},{"package":{"name":"tcpreplay","ecosystem":"Debian:14","purl":"pkg:deb/debian/tcpreplay?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2018-17974.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
