SCA: security update for github.com/ipfs/go-merkledag (GHSA-x39j-h85h-3f46)

high Tenable Self-Hosted Container Security Plugin ID 420244

Description

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

 - go-merkledag implements the 'DAGService' interface and adds two ipld node types, Protobuf and Raw for the
 ipfs project. A `ProtoNode` may be modified in such a way as to cause various encode errors which will
 trigger a panic on common method calls that don't allow for error returns. A `ProtoNode` should only be
 able to encode to valid DAG-PB, attempting to encode invalid DAG-PB forms will result in an error from the
 codec. Manipulation of an existing (newly created or decoded) `ProtoNode` using the modifier methods did
 not account for certain states that would place the `ProtoNode` into an unencodeable form. Due to
 conformance with the [`github.com/ipfs/go-block-format#Block`](https://pkg.go.dev/github.com/ipfs/go-
 block-format#Block) and [`github.com/ipfs/go-ipld-format#Node`](https://pkg.go.dev/github.com/ipfs/go-
 ipld-format#Node) interfaces, certain methods, which internally require a re-encode if state has changed,
 will panic due to the inability to return an error. This issue has been addressed across a number of pull
 requests. Users are advised to upgrade to version 0.8.1 for a complete set of fixes. Users unable to
 upgrade may attempt to mitigate this issue by sanitising inputs when allowing user-input to set a new
 `CidBuilder` on a `ProtoNode` and by sanitising `Tsize` (`Link#Size`) values such that they are a
 reasonable byte-size for sub-DAGs where derived from user-input. (CVE-2022-23495)
