VIR risk

5.0

Description

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.
