CVE-2026-54345 GoPacket's Diameter AVP decoder: uint32 underflow on vendor header size leads to unbounded ~4 GiB allocation (unauthenticated remote DoS)

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the Diameter AVP decoder computes an AVP data length by subtracting a fixed header size from an attacker-controlled AVP Length field, so a vendor-flagged AVP whose Length is smaller than the 12-byte header...

PT-2026-65535

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the sFlow ExtendedGatewayFlow decoder in layers/sflow.go reads an attacker-controlled 32-bit community count and AS path member count and sizes a slice allocation from those counts without bounding them against...

Network-based DNS logging in Go: GoPassiveDNS

A network-capture based DNS logger, inspired by passivedns. It uses gopacket to deal with libpcap and packet processing. It outputs JSON logs. It is intended to deal with high volume query capture in environments with anywhewre from one to hundreds of DNS resolvers. Why not use PassiveDNS from...
