SCA: security update for github.com/libp2p/go-libp2p (GHSA-876p-8259-xjgg)

high Tenable Self-Hosted Container Security Plugin ID 412502

Description

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

 - go-libp2p is the Go implementation of the libp2p Networking Stack. Prior to versions 0.27.8, 0.28.2, and
 0.29.1 malicious peer can use large RSA keys to run a resource exhaustion attack & force a node to spend
 time doing signature verification of the large key. This vulnerability is present in the core/crypto
 module of go-libp2p and can occur during the Noise handshake and the libp2p x509 extension verification
 step. To prevent this attack, go-libp2p versions 0.27.8, 0.28.2, and 0.29.1 restrict RSA keys to <= 8192
 bits. To protect one's application, it is necessary to update to these patch releases and to use the
 updated Go compiler in 1.20.7 or 1.19.12. There are no known workarounds for this issue. (CVE-2023-39533)
