Advisories for Golang/Github.com/Ipld/Go-Codec-Dagpb package

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-g3vv-g2j5-45f2. This link is maintained to preserve external references. Original Description go-codec-dagpb is an implementation of the DAG-PB spec for Go. The dag-pb codec can panic when decoding invalid blocks. This issue has been patched in version 1.3.1.

Decoding certain blocks using the go-ipld-prime version of the dag-pb codec (go-codec-dagpb) can cause a panic. The panic comes from an assumption that the reported link length is accurate, but if the block ends before that reported length then it’s a buffer overread.

This advisory duplicates another.
