Subject: [PATCH v2 0/2] fix read memory access overflow in HTTPBoot
Date: Fri, 28 Sep 2018 11:02:33 +0800 [thread overview]
Message-ID: <20180928030235.1080-1-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.
