{"schemaVersion":3,"id":"MGASA-2019-0094","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Updated tcpreplay packages fix security vulnerability\n\nAn issue was discovered in Tcpreplay 4.3.0 beta1. A heap-based buffer\nover-read was triggered in the function dlt_en10mb_encode() of the file\nplugins/dlt_en10mb/en10mb.c, due to inappropriate values in the function\nmemmove(). The length (pktlen + ctx -> l2len) can be larger than source\nvalue (packet + ctx->l2len) because the function fails to ensure the length\nof a packet is valid. This leads to Denial of Service. (CVE-2018-17974)\n\nA heap-based buffer over-read exists in the function fast_edit_packet() in\nthe file send_packets.c of Tcpreplay v4.3.0 beta1. This can lead to Denial\nof Service (DoS) and potentially Information Exposure when the application\nattempts to process a crafted pcap file. (CVE-2018-17580)\n\nTcpreplay v4.3.0 beta1 contains a heap-based buffer over-read. The\nget_next_packet() function in the send_packets.c file uses the memcpy()\nfunction unsafely to copy sequences from the source buffer pktdata to the\ndestination (*prev_packet)->pktdata. This will result in a Denial of\nService (DoS) and potentially Information Exposure when the application\nattempts to process a file. (CVE-2018-17582)\n\nA heap-based buffer over-read was discovered in the tcpreplay-edit binary\nof Tcpreplay 4.3.0 beta1, during the incremental checksum operation. The\nissue gets triggered in the function csum_replace4() in\nincremental_checksum.h, causing a denial of service. (CVE-2018-18407)\n\nA use-after-free was discovered in the tcpbridge binary of Tcpreplay 4.3.0\nbeta1. The issue gets triggered in the function post_args() at tcpbridge.c,\ncausing a denial of service or possibly unspecified other impact.\n(CVE-2018-18408)","dates":{"published":"2019-02-20T22:18:01.000Z","modified":"2026-04-16T04:40:52.741Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"tcpreplay","name":"tcpreplay","label":"tcpreplay","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/tcpreplay","purlType":"rpm","versions":[{"text":"< 4.3.1-1.mga6","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 4.3.1-1.mga6","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2019-0094.html","label":"advisories.mageia.org/MGASA-2019-0094.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=24148","label":"bugs.mageia.org/show_bug.cgi?id=24148","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/5UTDLO275Z67H3IN6UL57U6OAI4R3G5I/","label":"lists.fedoraproject.org/archives/…","hostname":"lists.fedoraproject.org","tags":["WEB"]}],"lineage":{"upstream":["CVE-2018-17580","CVE-2018-17582","CVE-2018-17974","CVE-2018-18407","CVE-2018-18408"],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2019-02-20T22:18:01.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T04:40:52.741Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T08:30:36.721Z","stale":false,"partial":false}}
