CVE-2025-2259

Eclipse ThreadX NetX Duo component HTTP server single PUT request integer underflow

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.
