Summary

A flaw was found in pulp-rpm when it publishes a distribution tree. Addon and variant ids from .treeinfo are used as directory names. A user who can sync or upload that tree can make the publish task create a new directory outside the task work area and write that tree's repository metadata and packages there, as the Pulp worker user. An existing file or directory is not replaced. The flaw does not disclose data and does not stop the service.

Risk Assessment

An attacker can cause files to be written outside the intended area, potentially leading to unauthorized data writes in the system, but it does not affect confidentiality or service availability.

Recommendation

Update pulp-rpm to a patched version and restrict sync/upload permissions for distribution trees to trusted users.
