"According to the versions of the binutils packages installed, the EulerOS Virtualization installation on the remote host
is affected by the following vulnerabilities :
- An out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this
flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in
some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system
availability. (CVE-2021-3549)
