What it is

In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before

version 6.4.3, an attacker can cause an integer underflow and a

subsequent denial of service by writing a very large file, by specially

crafted packets with Content-Length in one packet smaller than the data

request size of the other packet. A possible workaround is to disable

HTTP PUT support.

This issue follows an incomplete fix of CVE-2025-0727
