"The remote NewStart CGSL host, running version MAIN 6.02, has dnf packages installed that are affected by a
vulnerability:
- A flaw was found in libdnf's signature verification functionality. 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. (CVE-2021-3445)
