NVD Description

Note: Versions mentioned in the description apply only to the upstream rpm-libs package and not the rpm-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

It was found that versions of rpm before 4.13.0.2 use temporary files with predictable names when installing an RPM. An attacker with ability to write in a directory where files will be installed could create symbolic links to an arbitrary location and modify content, and possibly permissions to arbitrary files, which could be used for denial of service or possibly privilege escalation.
