apache -- Prevent chunk-size integer overflow on platforms where sizeof(int) < sizeof(long)

Description:

Apache ChangeLog reports:

Integer overflow in the ap_proxy_send_fb function in proxy/proxy_util.c in mod_proxy in the Apache HTTP Server before 1.3.42 on 64-bit platforms allows remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a large chunk size that triggers a heap-based buffer overflow.
