Overview

Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) when the WINPR_ASSERT function is used inappropriately. An attacker can cause a Denial of Service (DoS) by exploiting an Integer Underflow, which occurs when an insufficient blockLen is provided and proper length validation is not performed.
