CVE-2023-39540

Estado: ModificadaMedia (5.9)—

A denial of service vulnerability exists in the ICMP and ICMPv6 parsing functionality of Weston Embedded uC-TCP-IP v3.06.01. A specially crafted network packet can lead to an out-of-bounds read. An attacker can send a malicious packet to trigger this vulnerability.This vulnerability concerns a denial of service within the parsing an IPv4 ICMP packet.
