CVE-2025-51005

A heap-buffer-overflow vulnerability exists in the tcpliveplay utility of the tcpreplay-4.5.1. When a crafted pcap file is processed, the program incorrectly handles memory in the checksum calculation logic at dochecksummathliveplay in tcpliveplay.c, leading to a possible denial of service...

tsharkVM - Tshark + ELK Analytics Virtual Machine

This project builds virtual machine which can be used for analytics of tshark -T ek ndjson output. The virtual appliance is built using vagrant, which builds Debian 10 with pre-installed and pre-configured ELK stack. After the VM is up, the process is simple: decoded pcaps tshark -T ek output /...

Mutiny Fuzzing Framework - Network Fuzzer That Operates By Replaying PCAPs Through A Mutational Fuzzer

The Mutiny Fuzzing Framework is a network fuzzer that operates by replaying PCAPs through a mutational fuzzer. The goal is to begin network fuzzing as quickly as possible, at the expense of being thorough. The general workflow for Mutiny is to take a sample of legitimate traffic, such as a browse...

tcpdump < 4.9.3 - Multiple Heap-Based Out-of-Bounds Reads

Through fuzzing of network capture .pcap files, we have identified 16 crashes with unique stack traces in tcpdump. These crashes are caused by heap-based out-of-bounds memory reads, and can be reproduced with the latest tcpdump source code from GitHub, compiled with AddressSanitizer: --- cut --- ...

tcpdump: multiple overflow issues in protocol decoding

Multiple out of bounds read and integer overflow vulnerabilities were found in tcpdump affecting the decoding of various protocols. An attacker could create a crafted pcap file or send specially crafted packets to the network segment where tcpdump is running in live capture mode without -w which...
