## Description

The proxy functionality in (1) mod\_proxy\_ajp.c in the mod\_proxy\_ajp module
and (2) mod\_proxy\_http.c in the mod\_proxy\_http module in the Apache HTTP
Server 2.4.x before 2.4.3 does not properly determine the situations that
require closing a back-end connection, which allows remote attackers to
obtain sensitive information in opportunistic circumstances by reading a
response that was intended for a different client.
