Type: security
Affected Mageia releases : 6
CVE: CVE-2018-17974 , CVE-2018-17580 , CVE-2018-17582 , CVE-2018-18407 , CVE-2018-18408
Description
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 -> l2len) can be larger than source value (packet + ctx->l2len) because the function fails to ensure the length of a packet is valid. This leads to Denial of Service. (CVE-2018-17974) A heap-based buffer over-read exists in the function fast_edit_packet() in the file send_packets.c of Tcpreplay v4.3.0 beta1. This can lead to Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a crafted pcap file. (CVE-2018-17580) 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)->pktdata. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a file. (CVE-2018-17582) A heap-based buffer over-read was discovered in the tcpreplay-edit binary of Tcpreplay 4.3.0 beta1, during the incremental checksum operation. The issue gets triggered in the function csum_replace4() in incremental_checksum.h, causing a denial of service. (CVE-2018-18407) A use-after-free was discovered in the tcpbridge binary of Tcpreplay 4.3.0 beta1. The issue gets triggered in the function post_args() at tcpbridge.c, causing a denial of service or possibly unspecified other impact. (CVE-2018-18408)
