Alpine: multiple rpm packages, py3-rpm: security update to 4.17.1-r0

medium Tenable Cloud Security Plugin ID 406943

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)
