Description Robert Frohl 2021-01-26 15:19:52 UTC
CVE-2021-21272

ORAS is open source software which enables a way to push OCI Artifacts to OCI
Conformant registries. ORAS is both a CLI for initial testing and a Go Module.

In ORAS from version 0.4.0 and before version 0.9.0, there is a "zip-slip"
vulnerability.

The directory support feature allows the downloaded gzipped tarballs to be
automatically extracted to the user-specified directory where the tarball can
have symbolic links and hard links.

A well-crafted tarball or tarballs allow malicious artifact providers linking,
writing, or overwriting specific files on the host filesystem outside of the
user-specified directory unexpectedly with the same permissions as the user who
runs `oras pull`. 

Users of the affected versions are impacted if they are `oras` CLI users who
runs `oras pull`, or if they are Go programs, which invoke
`github.com/deislabs/oras/pkg/content.FileStore`.

The problem has been fixed in version 0.9.0.

For `oras` CLI users, there is no workarounds other than pulling from a trusted
artifact provider.

For `oras` package users, the workaround is to not use
`github.com/deislabs/oras/pkg/content.FileStore`, and use other content stores
instead, or pull from a trusted artifact provider.

Comment 2 Dirk Mueller 2021-01-26 19:19:08 UTC
Not only please note that oras is a golang module that is embedded in plenty of modules like for example but not limited to singularity and helm.
Comment 3 Dirk Mueller 2021-01-26 19:46:32 UTC
Submitted change for harbor upstream: https://github.com/goharbor/harbor/pull/14092

Helm is missing it as well: https://github.com/helm/helm/pull/9269
