Vulnerability Details

CVEID:CVE-2021-3521
**DESCRIPTION:**RPM Project RPM could allow a remote attacker to bypass security restrictions, caused by improper validation the binding signature of subkeys prior to importing them. By persuading a victim to add a specially-crafted subkey to a legitimate public key, an attacker could exploit this vulnerability cause the victim to trust a malicious signature.
