Overview

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to inefficient complexity in the htp_process_response_header_generic() function in htp/htp_response_generic.c. An attacker can deny service by sending excessive HTTP headers, which slow down the application.
