NVD Description

Note: Versions mentioned in the description apply only to the upstream libdnf package and not the libdnf package as distributed by Ubuntu.

A flaw was found in libdnf's signature verification functionality in versions before 0.60.1.

The highest risk of this vulnerability is to confidentiality, integrity, as well as system availability.
