Vulnerabilidades

lwIP (Lightweight IP) has a double free vulnerability, which could crash the system, cause a DoS, memory corruption, or allow code execution on the victim system.

lwIP TCP/IP Stack MQTT is vulnerable to an out-of-bounds write, which may allow an attacker to gain full code execution on the device.

A vulnerability was found in lwIP up to 2.2.1. Affected is the function snmp_parse_inbound_frame of the file src/apps/snmp/snmp_msg.c of the component snmpv3 USM Handler. Performing a manipulation of the argument msgAuthenticationParameters results in stack-based buffer overflow. The attack may be initiated remotely.…

A buffer overflow vulnerability in the zepif_linkoutput() function of Free Software Foundation lwIP git head version and version 2.1.2 allows attackers to access sensitive information via a crafted 6LoWPAN packet.

A buffer overflow vulnerability in the icmp6_send_response_with_addrs_and_netif() function of Free Software Foundation lwIP version git head allows attackers to access sensitive information via a crafted ICMPv6 packet.

prebuild-lwip is a module for comprehensive, fast, and simple image processing and manipulation. prebuild-lwip downloads resources over HTTP, which leaves it vulnerable to MITM attacks.

resolv.c in the DNS resolver in uIP, and dns.c in the DNS resolver in lwIP 1.4.1 and earlier, does not use random values for ID fields and source ports of DNS query packets, which makes it easier for man-in-the-middle attackers to conduct cache-poisoning attacks via spoofed reply packets.
