Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerability :
- An out-of-bounds write vulnerability was found in glibc
before 2.31 when handling signal trampolines on
PowerPC. Specifically, the backtrace function did not
properly check the array bounds when storing the frame
address, resulting in a denial of service or potential
code execution. The highest threat from this
vulnerability is to system availability.(CVE-2020-1751)
