Vulnerability from variot
A vulnerability has been identified in Nucleus NET (All versions), Nucleus ReadyStart V3 (All versions < V2013.08), Nucleus Source Code (Versions including affected DNS modules). The DNS client does not properly randomize UDP port numbers of DNS requests. That could allow an attacker to poison the DNS cache or spoof DNS resolving. The Nucleus NET module contains a series of standard-compliant network and communication protocols, drivers and utilities to provide full-featured network support in any embedded device. Nucleus RTOS provides a highly scalable microkernel-based real-time operating system designed for the scalability and reliability of systems in aerospace, industrial and medical applications. VSTAR is a complete AUTOSAR 4 based ECU solution that provides tools and embedded software for timely product deployment. Nucleus ReadyStart is a platform with integrated software IP, tools and services.
The DNS module of Siemens Nucleus products has security vulnerabilities. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements
