Broadcom: >> Tcpreplay Security Vulnerabilities
An issue was discovered in Tcpreplay 4.3.1. An invalid memory access occurs in do_checksum in checksum.c. It can be triggered by sending a crafted pcap file to the tcpreplay-edit binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.

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.

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.

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.
