What is CVE-2020-15472?

A vulnerability exists in nDPI versions up to 3.2 where the H.323 dissector is susceptible to a heap-based buffer over-read. This can occur in the ndpi_search_h323 function, particularly when a payload packet's length is shorter than expected. As a result, this may lead to unintended access to memory beyond the allocated buffers, potentially allowing for further exploitation or denial of service. It is crucial for users of nDPI to update to the latest version to avoid these risks.
