{"id":"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":"2026-04-16T04:35:54.917584347Z","published":"2018-09-28T09:29:01.057Z","related":["openSUSE-SU-2024:11426-1"],"references":[{"type":"FIX","url":"https://github.com/appneta/tcpreplay/issues/484"},{"type":"EVIDENCE","url":"https://github.com/SegfaultMasters/covering360/blob/master/tcpreplay"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/appneta/tcpreplay","events":[{"introduced":"0"},{"last_affected":"b663095bd87b60822d4b8688a48040c8f88fd045"},{"introduced":"0"},{"last_affected":"50aa4e176c4ea6f7544bc00bf0c50613bdd31d9d"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"4.3.0-beta1"},{"introduced":"0"},{"last_affected":"4.3.0-beta2"}]}}],"versions":["v3.4.2","v3.4.3","v3.4.4","v4.0.0","v4.0.0beta1","v4.0.0beta2","v4.0.1","v4.0.2","v4.0.3","v4.0.4","v4.0.5","v4.0.5beta1","v4.0.5beta2","v4.0.5beta3","v4.1.0","v4.1.0beta1","v4.1.0beta2","v4.1.1","v4.1.1-beta2","v4.1.1-beta3","v4.1.2","v4.2.6","v4.3.0-beta1","v4.3.0-beta2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-17582.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"}]}
