Summary
Path traversal in github.com/ipfs/go-ipfs
Details

Impact

It is currently possible for path traversal to occur with DAGs containing relative paths during retrieval. This can cause files to be overwritten, or written to incorrect output directories. The issue can only occur when ipfs get is done on an affected DAG.

  1. The only affected command is ipfs get.
  2. The gateway is not affected.

Patches

Traversal fix patched in https://github.com/whyrusleeping/tar-utils/commit/20a61371de5b51380bbdb0c7935b30b0625ac227 tar-utils patch applied to go-ipfs via https://github.com/ipfs/go-ipfs/commit/b7ddba7fe47dee5b1760b8ffe897908417e577b2

Workarounds

Upgrade to go-ipfs 0.8 or later.
