Description

rpm security update

The RPM Package Manager (RPM) is a powerful package management system capability as below

Security Fix(es):

The OpenPGP subkey is associated with the master key through a binding signature. RPM will not check their binding signature before importing the subkey; if the attacker can add it or the other party of social engineering adds the malicious subkey to the legal public Key, RPM may mistakenly trust malicious signatures.(CVE-2021-3521)
