CUJO Smart Firewall mdnscap mDNS character-strings code execution vulnerability

Summary An exploitable heap overflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. The string lengths are handled incorrectly when parsing character strings in mDNS resource records, leading to arbitrary code execution in the context of the mdnscap...

CUJO Smart Firewall mdnscap mDNS record parsing code execution vulnerability

Summary An exploitable double free vulnerability exists in the mdnscap binary of the CUJO Smart Firewall. When parsing mDNS packets, a memory space is freed twice if an invalid query name is encountered, leading to arbitrary code execution in the context of the mdnscap process. An unauthenticated...

PFQ - Functional Network Framework For Multi-Core Architectures

PFQ is a functional framework designed for the Linux operating system built for efficient packets capture/transmission 10G, 40G and beyond, in-kernel functional processing, kernel-bypass and packets steering across groups of sockets/end-points.

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 --- ...
