USN-5454-1: CUPS vulnerabilities

31 May 2022

Several security issues were fixed in CUPS.



  • cups - Common UNIX Printing System(tm)


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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04
Ubuntu 21.10
Ubuntu 20.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
