EulerOS Virtualization 2.10.1 : rpm (EulerOS-SA-2022-1386)

medium Nessus Plugin ID 159874

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the rpm packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected rpm packages.
