Subject: [PATCH 0/2] fix read memory access overflow in HTTPBoot.
Date: Tue, 25 Sep 2018 16:24:38 +0800	[thread overview]
Message-ID: <20180925082440.20416-1-songpeng.li@intel.com> (raw)

The input param String of AsciiStrStr() requires a pointer to
 Null-terminated string, however in HttpTcpReceiveHeader() and
 HttpUtilitiesParse(), the Buffersize before AllocateZeroPool()
 is equal to the size of TCP header, after the CopyMem(), it
 might not end with Null-terminator. It might cause memory
 access overflow.

  NetworkPkg/HttpDxe: fix read memory access overflow in HTTPBoot.
  NetworkPkg/HttpUtilitiesDxe: fix read memory access overflow.
