SCA: security update for github.com/gopacket/gopacket (GHSA-6r28-9ppf-4hj5)

medium Tenable Self-Hosted Container Security Plugin ID 445395

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 underflows the
 unsigned 32-bit value and drives an unbounded allocation of roughly 4 GiB, and two such messages in
 succession OOM-kill a collector, causing an unauthenticated remote denial of service. This issue is fixed
 in version 1.6.1. (CVE-2026-54345)

Solution

Update the github.com/gopacket/gopacket library and its related packages to version 1.6.1 or later.
