  * SECURITY UPDATE: heap-based buffer over-read
    - debian/patches/CVE-2022-37434-1.patch: in inflate.c, add an extra
      condition to check if state->head->extra_max is greater than len
      before copying, and move the len assignment to be placed before the
      check.
    - debian/patches/CVE-2022-37434-2.patch: in the previous patch, in
      inflate.c, the place of the len assignment was causing issues so it
      was moved to be placed within the check.
