{"id":"DEBIAN-CVE-2018-17582","details":"Tcpreplay v4.3.0 beta1 contains a heap-based buffer over-read. The get_next_packet() function in the send_packets.c file uses the memcpy() function unsafely to copy sequences from the source buffer pktdata to the destination (*prev_packet)-\u003epktdata. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a file.","modified":"2026-09-01T16:04:40.348891653Z","published":"2018-09-28T09:29:01.057Z","upstream":["CVE-2018-17582"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-17582"}],"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-2018-17582.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-2018-17582.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-2018-17582.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:H/I:N/A:H"}]}
