According to the versions of the rpm packages installed, the EulerOS 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.
