Summary

ipld/go-codec-dagpb panics when processing certain blocks

Details

Impact

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.

Patches

The issue is fixed in v1.3.1 and above.

Consumers can discover the versions of go-codec-dagpb in a module's dependency graph using the following command in the module root:

go mod graph | grep go-codec-dagpb

Workarounds

You can work around this issue without upgrading by recovering panics higher in the call stack of the goroutine that calls the defective code.
