NVD Description

Note: Versions mentioned in the description apply only to the upstream rpm package and not the rpm package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A symbolic link issue was found in rpm. It occurs when rpm sets the desired permissions and credentials after installing a file. A local unprivileged user could use this flaw to exchange the original file with a symbolic link to a security-critical file and escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
