Releases
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
Ubuntu 22.04
Ubuntu 20.04
In general, a standard system update will make all the necessary changes.
