Descriptions
Buffer overflow in HAProxy 1.4 through 1.4.22 and 1.5-dev through 1.5-dev17, when HTTP keep-alive is enabled, using HTTP keywords in TCP inspection rules, and running with rewrite rules that appends to requests, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted pipelined HTTP requests that prevent request realignment from occurring.
Desbordamiento de búfer en HAProxy v1.4 y v1.5 mediante v1.5-dev17 través de 1.5-dev17 al mantenimiento de conexión está habilitado, mediante palabras clave HTTP en las reglas de inspección de TCP, y corriendo con las reglas con reescritura, que se anexan a las solicitudes, permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de peticiones pipeline HTTP diseñadas a medida que se produzca la realineación.
HAProxy provides high availability, load balancing, and proxying for TCP and HTTP-based applications. A buffer overflow flaw was found in the way HAProxy handled pipelined HTTP requests. A remote attacker could send pipelined HTTP requests that would cause HAProxy to crash or, potentially, execute arbitrary code with the privileges of the user running HAProxy. This issue only affected systems using all of the following combined configuration options: HTTP keep alive enabled, HTTP keywords in TCP inspection rules, and request appending rules.
