Vulnerability from variot
A vulnerability has been identified in Capital Embedded AR Classic 431-422 (All versions), Capital Embedded AR Classic R20-11 (All versions < V2303), Nucleus NET (All versions), Nucleus ReadyStart V3 (All versions < V2017.02.4), Nucleus ReadyStart V4 (All versions < V4.1.0), Nucleus Source Code (All versions including affected IPv6 stack). The function that processes the Hop-by-Hop extension header in IPv6 packets and its options lacks any checks against the length field of the header, allowing attackers to put the function into an infinite loop by supplying arbitrary length values. 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.
Siemens Nucleus products have security vulnerabilities. An attacker can use the vulnerability to put the function into infinity by providing an arbitrary length value. 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
