An issue found in TCPprep v.4.4.3 allows a remote attacker to cause a denial of service via the macinstring function.

An issue found in TCPprep v.4.4.3 allows a remote attacker to cause a denial of service via the cidr2cidr function at the cidr.c:178 endpoint.

An issue found in TCPReplay v.4.4.3 allows a remote attacker to cause a denial of service via the readhexstring function at the utils.c:309 endpoint.

An issue found in TCPrewrite v.4.4.3 allows a remote attacker to cause a denial of service via the ports2PORT function at the portmap.c:69 endpoint.

An issue found in TCPprep v.4.4.3 allows a remote attacker to cause a denial of service via the parselist function at the list.c:81 endpoint.

An issue found in TCPreplay TCPprep v.4.4.3 allows a remote attacker to cause a denial of service via the parse endpoints function.

An issue found in TCPreplay tcprewrite v.4.4.3 allows a remote attacker to cause a denial of service via the tcpeditdltcleanup function at plugins/dltplugins.c.

Heap-buffer overflow in the randomizeiparp function in editpacket.c. of Tcpreplay v4.3.2 allows attackers to cause a denial of service (DOS) via a crafted pcap.

Buffer Overflow in Tcpreplay v4.3.2 allows attackers to cause a Denial of Service via the 'dochecksum' function in 'checksum.c'. It can be triggered by sending a crafted pcap file to the 'tcpreplay-edit' binary. This issue is different than CVE-2019-8381.

Tcpreplay before 4.3.1 has a heap-based buffer over-read in packet2tree in tree.c.

Tcpreplay before 4.3.1 has a heap-based buffer over-read in getl2len in common/get.c.

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 csumreplace4() in incrementalchecksum.h, causing a denial of service.

A use-after-free was discovered in the tcpbridge binary of Tcpreplay 4.3.0 beta1. The issue gets triggered in the function postargs() at tcpbridge.c, causing a denial of service or possibly unspecified other impact.

An issue was discovered in Tcpreplay 4.3.0 beta1. A heap-based buffer over-read was triggered in the function dlten10mbencode() of the file plugins/dlten10mb/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 getnextpacket() function in the sendpackets.c file uses the memcpy() function unsafely to copy sequences from the source buffer pktdata to the destination (prevpacket)->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 fasteditpacket() in the file sendpackets.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.

getl2len in common/get.c in Tcpreplay 4.3.0 beta1 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via crafted packets, as demonstrated by tcpprep.

tcprewrite in Tcpreplay 3.4.4 has a Heap-Based Buffer Overflow vulnerability triggered by a crafted PCAP file, a related issue to CVE-2016-6160.
