CVE-2020-25111

An issue was discovered in the IPv6 stack in Contiki through 3.0. There is an insufficient check for the IPv6 header length. This leads to Denial-of-Service and potential Remote Code Execution via a crafted ICMPv6 echo packet...

CVE-2020-17443

CVE-2020-17443 affects picoTCP 1.7.0 (and picoTCP-NG) where ICMPv6 echo reply creation does not validate that the request header is at least 8 bytes. If a request is shorter than 8 bytes, an integer wraparound occurs when sizing the echo reply, causing memory corruption and potential DoS in pico_...

CVE-2020-17443

An issue was discovered in picoTCP 1.7.0. The code for creating an ICMPv6 echo replies doesn't check whether the ICMPv6 echo request packet's size is shorter than 8 bytes. If the size of the incoming ICMPv6 request packet is shorter than this, the operation that calculates the size of the ICMPv6...

CVE-2020-17441

An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 headers does not validate whether the IPv6 payload length field is equal to the actual size of the payload, which leads to an Out-of-Bounds read during the ICMPv6 checksum calculation, resulting in either Denial-of-Service...

CVE-2020-17441

CVE-2020-17441 affects picoTCP 1.7.0, specifically the IPv6 processing code in pico_ipv6_extension_headers and pico_checksum_adder (pico_ipv6.c, pico_frame.c). The issue arises from not validating the IPv6 payload length against the actual payload when computing the ICMPv6 checksum, causing an ou...

FreeBSD : FreeBSD -- ICMPv6 use-after-free in error message handling (8eed0c5c-3482-11eb-b87a-901b0ef719ab)

When an ICMPv6 error message is received, the FreeBSD ICMPv6 stack may extract information from the message to hand to upper-layer protocols. As a part of this operation, it may parse IPv6 header options from a packet embedded in the ICMPv6 message. The handler for a routing option caches a point...
