CVE-2018-10897
Published: 1 August 2018
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.
