Vulnerability from github – Published: 2022-05-24 17:48 – Updated: 2025-03-11 12:30

Details

A vulnerability has been identified in Nucleus 4 (All versions < V4.1.0), Nucleus NET (All versions), Nucleus ReadyStart (All versions), Nucleus Source Code (versions including affected IPv6 stack), VSTAR (versions including affected IPv6 stack). The function that processes IPv6 headers does not check the lengths of extension header options, allowing attackers to put this function into an infinite loop with crafted length values.
