Descrição técnica

In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a, built with BSD raw socket and IPv6 support, the IPv6 raw send path uses the destination-table entry it adds without checking that the add succeeded. When the destination table is full and an off-link destination is reached through a default router whose neighbour cache entry is unknown, sending on an IPv6 raw socket with header inclusion dereferences a NULL pointer; a remote sender can fill the table, for example with ICMPv6 Packet Too Big messages, and crash the sending thread.

——7NULL Pointer Dereference (CWE-476) in the AMQP protocol parser in Packetbeat can lead to denial of service via specially crafted network traffic. An unauthenticated attacker who can send traffic on a network segment that Packetbeat monitors for AMQP can cause a Go runtime panic that terminates the Packetbeat process. A single crafted packet is sufficient. No AMQP authentication is necessary. While Packetbeat is not running, it does not collect network telemetry.2d
