Description

In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before <br /> version 6.4.2, an attacker can cause an integer underflow and a <br /> subsequent denial of service by writing a very large file, by specially <br /> crafted packets with Content-Length in one packet smaller than the data <br /> request size of the other packet. A possible workaround is to disable <br /> HTTP PUT support.
