Upgrade Debian:11 libplist to version 1.12+git+1+e37ca00-0.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libplist package and not the libplist package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
The plist_free_data function in plist.c in libplist allows attackers to cause a denial of service (crash) via vectors involving an integer node that is treated as a PLIST_KEY and then triggers an invalid free.
