Description
A flaw was found in oc-mirror's legacy v1 catalog cache rebuild. When the --build-catalog-cache flag is used, oc-mirror extracts an opm binary from the remote operator catalog image and executes it on the host without verifying its signature, digest, or integrity. An attacker who publishes a malicious catalog image to a registry could supply a trojanized opm binary that is executed with the privileges of the user running oc-mirror, resulting in arbitrary code execution on the mirroring host.
