Resolution: Fixed
Fix Version/s: 1.1.3
Revision 1640524
> Remove the MongoGridFSBlobStore implementation
> ----------------------------------------------
>
> Key: OAK-2107
> URL: https://issues.apache.org/jira/browse/OAK-2107
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: mongomk
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Minor
> Fix For: 1.2, 1.1.3
>
>
> The MongoGridFSBlobStore implementation relies on using MD5 as the content
> hash, which is dangerous. This isn't a problem of GridFS itself, but of
> MongoGridFSBlobStore.
> For security reasons, we would need to use SHA-2 (or at least SHA-1). It
> doesn't look like it would be easy to change MongoGridFSBlobStore, because
> "md5" is used internally by GridFS (but not actually as the content hash).
> So either we make a bigger change to MongoGridFSBlobStore, or we remove it. I
> think we should remove it, as we have a good alternative (the MongoBlobStore,
> which uses SHA-256, but not GridFS).
