There is no fixed version for Debian:13 ndpi.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ndpi package and not the ndpi package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service.
