  # nb:
  # - The MDEV issue also includes "11.8.2" in the "Fix Version/s:" box but the changelog doesn't
  #   include any reference to this CVE. Furthermore later 11.5 - 11.7 changelogs are also not
  #   including it so it is currently assumed that 11.4.x was the last affected branch.
  # - As the relevant CVE-2023-52969 and CVE-2023-52970 also got fixed in e.g. 10.5.29 at the same
  #   time it is currently assumed that this CVE here only affected the 10.10.x, 10.11.x, 11.0.x and
  #   11.1.x branches
