  - CVE-2020-25717: A flaw was discovered in the way Samba maps domain users to local users. An
  authenticated attacker could use this flaw to gain potential privilege escalation. Addressed this
  vulnerability by updating Debian (buster) version to 2:4.9.5+dfsg-5+deb10u2.

  - CVE-2020-21913: A use-after-free vulnerability was found in the International Components for
  Unicode (ICU) library which could result in denial of service or potentially the execution of
  arbitrary code. Addressed this vulnerability by updating the Debian (buster) version to
  63.1-6+deb10u2.

  - CVE-2022-22989: My Cloud OS 5 was vulnerable to a pre-authenticated stack overflow vulnerability
  on the FTP service. Addressed the vulnerability by adding defenses against stack overflow issues.

  - CVE-2022-22990, CVE-2022-22992, CVE-2022-22993: A limited authentication bypass vulnerability
  was discovered that could allow an attacker to achieve remote code execution and escalate
  privileges on the My Cloud devices. Addressed this vulnerability by changing access token
  validation logic and rewriting rule logic on PHP scripts.

  - CVE-2022-22991, CVE-2022-22994: A malicious user on the same LAN could use DNS spoofing followed
  by a command injection attack to trick a NAS device into loading through an unsecured HTTP call.
  Addressed this vulnerability by disabling checks for internet connectivity using HTTP.

  - CVE-2022-0194, CVE-2022-23121, CVE-2022-23122, CVE-2022-23123, CVE-2022-23124, CVE-2022-23125,
