Bump github.com/gopacket/gopacket from 1.7.0 to 1.7.1

[dependabot]

Bumps github.com/gopacket/gopacket from 1.7.0 to 1.7.1.

Release notes

Sourced from github.com/gopacket/gopacket's releases.

v1.7.1

Security release. All versions up to and including v1.7.0 are affected — upgrade is recommended for anyone decoding untrusted packets or capture files.

Security fixes

Crafted input caused runtime panics (out-of-bounds slice/index, or unsigned underflow producing an inverted range) in a number of layers/ decoders. Each is now bounded against the buffer, returning a decode error and setting SetTruncated() instead of crashing.

Advisory	Area
CVE-2026-65819	TLS, DHCPv4, sFlow, IPSecAH, VRRPv2, Diameter, GTPv1U, ERSPAN, LCM, RadioTap, Dot11IE — the fix for this shipped in no prior release
GHSA-6h9g-cjv3-pg2c	TCP MPTCP options — on the ordinary Ethernet→IP→TCP path, so any consumer decoding untrusted TCP was exposed
GHSA-25xj-ggj7-jqgf	SIP header folding (port-auto-selected, single UDP datagram)
GHSA-cxrr-2gv2-m94w	EtherIP, AGUEVar0, UDPLite, MPLS, EthernetCTP, PFLog, LinuxSLL, LinuxSLL2, PktapV1, Prism, PPP, FDDI

Note on exposure: gopacket.NewPacket with default options and DecodingLayerParser with IgnorePanic: false both recover, so those callers previously saw a decode error rather than a crash. A process crash landed on a direct DecodeFromBytes call, IgnorePanic: true, or SkipDecodeRecovery: true.

The GHSA-cxrr decoders split by trust model: the first five carry remote-attacker-controlled bytes, while PFLog, LinuxSLL/SLL2, PktapV1, Prism, PPP and FDDI are written by the host's own capture stack, making a crafted pcap from an untrusted source the realistic input rather than a packet off the wire.

Other fixes

• Protocol decoder length checks across arp, ipsec, pppoe, rudp, sctp and vrrp (#163)
• MDNS name serialization fix (#157)
• Regression tests for DNS decodeSVCB truncated SvcParams, and for every advisory above

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a netobserv member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
