About this tag
The go libp2p tag covers discussions about the Go implementation of the libp2p networking stack, which is used in peer-to-peer projects like IPFS and blockchain applications. A prominent topic is CVE-2023-39533, a high-severity denial-of-service vulnerability discovered in August 2023. This flaw allows a malicious peer to cause CPU exhaustion by presenting oversized RSA keys (up to 8192 bits) during cryptographic handshakes, potentially crashing or making nodes unavailable until patched. The tag includes security advisories, patching guidance, and technical analysis of the vulnerability's impact on go-libp2p nodes.

    CVE-2023-39533 DoS in Go libp2p: RSA Key Size Cap at 8192 Bits

    A high‑impact denial‑of‑service condition was disclosed in August 2023 that allows a malicious peer to cripple go‑libp2p nodes by presenting oversized RSA keys during cryptographic handshakes — forcing affected nodes to spend excessive CPU time verifying signatures and, in many cases, driving...
