Overview
Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) in the ParseHttpHeaders process. An attacker can cause the application to read memory outside the bounds of the allocated HTTP request buffer by sending a specially crafted SOAPAction header containing a single quote, which exploits improper length validation and results in an out-of-bounds memory read.
