According to the version of the openssl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  • A null pointer dereference flaw was found in openssl. A remote attacker, able to control the arguments of the GENERAL_NAME_cmp function, could cause the application, compiled with openssl to crash resulting in a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2020-1971)

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.
