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.
- The only affected command is
ipfs get.
- The gateway is not affected.
Patches
Traversal fix patched in whyrusleeping/tar-utils@20a6137
tar-utils patch applied to go-ipfs via b7ddba7
Workarounds
Upgrade to go-ipfs 0.8 RC1 or later.
References
