Technical description
A directory traversal issue was found in reposync, a part of yum-utils, where reposync fails to sanitize paths in remote repository configuration files. If an attacker controls a repository, they may be able to copy files outside of the destination directory on the targeted system via path traversal. If reposync is running with heightened privileges on a targeted system, this flaw could potentially result in system compromise via the overwriting of critical system files. Version 1.1.31 and older are believed to be affected.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
