SCA: security update for github.com/osrg/gobgp/v4 (GHSA-p3w2-64xm-833j)

high Tenable Cloud Security Plugin ID 441234

Description

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

 - GoBGP is an open source Border Gateway Protocol (BGP) implementation in the Go Programming Language. In
 version 4.4.0, an unauthenticated remote BGP peer can trigger a fatal panic in GoBGP by sending a
 specially crafted BGP UPDATE message. When the server receives a message with inconsistent attribute
 lengths, it improperly handles the internal state transition to a "withdraw" action, leading to a nil
 pointer dereference in the AdjRib.Update function. This causes the entire GoBGP process to crash,
 resulting in a complete loss of service availability. This issue has been patched in version 4.5.0.
 (CVE-2026-42285)

Solution

Update the github.com/osrg/gobgp/v4 library and its related packages to version 4.5.0 or later.
