A flaw was found in libdnfs signature verification functionality in versions before 0.60.1. This flaw allows an attacker to achieve code execution if they can alter the header information of an RPM package and then trick a user or system into installing it. The highest risk of this vulnerability is to confidentiality, integrity, as well as system availability.
Weakness
