CVE-2024-4853Public exploit

Process crash via oversized memmove in handle_chopping

Published May 14, 2024 · Updated Mar 27, 2026

Heap-buffer overflow in Editcap 3.6.0 through 3.6.22, 4.0.0 through 4.0.14, and 4.2.0 through 4.2.4 allows attackers to crash it via a malformed file. The handle_chopping function passes memmove a length that reads beyond its heap allocation while removing bytes from the start of a packet. Exploitation requires a victim to run byte chopping on the malformed capture; the demonstrated consequence is an Editcap process crash.
