The Common UNIX Printing System (CUPS) provides a portable printing layer

for UNIX operating systems.

A use-after-free flaw was found in the way the CUPS server parsed Internet

Printing Protocol (IPP) packets. A malicious user able to send IPP requests

to the CUPS server could use this flaw to crash the CUPS server or,

potentially, execute arbitrary code with the privileges of the CUPS server.
