high Nessus Plugin ID 156520

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability. (CVE-2021-20271)

- A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects RPM versions before 4.17.0-alpha. (CVE-2021-3421)

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
