Releases
Packages

Details
It was discovered that libppd 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
libppd 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
In general, a standard system update will make all the necessary changes.
