The version of AOS installed on the remote host is prior to 5.15.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.15.3 advisory.

  - An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c. (CVE-2017-18595)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

  - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-     daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use     this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus     clients. (CVE-2020-12049)
