According to the version of the patch package 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 the way patch processed patch files. An attacker could potentially use this flaw to crash patch by tricking it into processing crafted patches.(CVE-2018-6951)

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.
