Hi Brian, LTS team, This was reported by the Ubuntu security team: The DLA 2550-1 update was aiming to fix CVE-2020-27844 as well, but it looks that whilst a patch is included in debian/patches the series files does not apply it.
To be on safe side I have removed the listing for CVE-2020-27844 in the DLA 2550-1, but please double-check if this is correct? Regards, Salvatore
