Descriptions

LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. Prior to version 0.5.49, unbounded processing of HTTP request and response headers can lead to excessive CPU time and memory utilization, possibly leading to extreme slowdowns. This issue is addressed in 0.5.49.

LibHTP es un analizador que tiene en cuenta la seguridad del protocolo HTTP y sus componentes relacionados. Antes de la versión 0.5.49, el procesamiento ilimitado de los encabezados de solicitud y respuesta HTTP podía generar un uso excesivo de la memoria y del tiempo de CPU, lo que posiblemente provocara ralentizaciones extremas. Este problema se solucionó en la versión 0.5.49.
