description

gopacket decoders can mishandle malformed OSPF, LLDP, TCP, and transport-header data, causing process termination or excessive memory use. An attacker must be able to provide network traffic to a capture or decoding workflow, or provide a capture file for processing.

mitigation

Upgrade github.com/gopacket/gopacket to version 1.7.5 or later. Until upgraded, reject untrusted capture input and avoid invoking packet or endpoint string formatting on packets with decoding errors.

fixed in 1.7.5
