"The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2022:0368 advisory.
- There is a flaw in RPM's signature functionality. OpenPGP subkeys are associated with a primary key via a
binding signature. RPM does not check the binding signature of subkeys prior to importing them. If an
attacker is able to add or socially engineer another party to add a malicious subkey to a legitimate
public key, RPM could wrongly trust a malicious signature. The greatest impact of this flaw is to data
integrity. To exploit this flaw, an attacker must either compromise an RPM repository or convince an
administrator to install an untrusted RPM or public key. It is strongly recommended to only use RPMs and
public keys from trusted sources. (CVE-2021-3521)
