A scan of this rock shows that it was built with packages from the Ubuntu
archive that have since received security updates. The following lists new
USNs for affected binary packages in each rock revision:
Revision r3a6f1d911103 (ppc64le; channels: 1.22-23.04_beta, 1.22-23.04_edge, edge, latest)
* tar: 5900-2
Revision r66791128e0ff (amd64; channels: 1.22-23.04_beta, 1.22-23.04_edge, edge, latest)
* tar: 5900-2
Revision r7ead9572a572 (arm64; channels: 1.22-23.04_beta, 1.22-23.04_edge, edge, latest)
* tar: 5900-2
Revision r931d316d5c25 (s390x; channels: 1.22-23.04_beta, 1.22-23.04_edge, edge, latest)

Simply rebuilding the rock will pull in the new security updates and
resolve this. If your rock also contains vendored code, now might be a
good time to review it for any needed updates.
Thank you for your rock and for attending to this matter.
