Original advisory details:

 Joshua Mason discovered that CUPS incorrectly handled the secret key used
 to access the administrative web interface. A remote attacker could
 possibly use this issue to open a session as an administrator and execute
 arbitrary code. (CVE-2022-26691)

 It was discovered that CUPS incorrectly handled certain memory operations
 when handling IPP printing. A remote attacker could possibly use this issue
 to cause CUPS to crash, leading to a denial of service, or obtain sensitive
 information. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04
 LTS. (CVE-2019-8842, CVE-2020-10001)");
