Releases

• Ubuntu 23.04
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• cups - Common UNIX Printing System(tm)

Details

It was discovered that CUPS incorrectly parsed certain Postscript objects.
If a user or automated system were tricked into printing a specially
crafted document, a remote attacker could use this issue to cause CUPS to
crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions

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

Ubuntu 23.04

• cups - 2.4.2-3ubuntu2.5

Ubuntu 22.04

• cups - 2.4.1op1-1ubuntu4.7

Ubuntu 20.04

• cups - 2.3.1-9ubuntu1.6

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