Overview
Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) through the handling of HTTP PUT requests. An attacker can cause a system crash and service disruption by sending specially crafted packets with a Content-Length header smaller than the actual data size.
Workaround
Users who are not able to upgrade to the fixed version can disable the processing of PUT requests by ending the processing of a PUT request in an application callback request notify function.
