From 2369bb02040a7aafd30b9f1c07624d605de65b1f Mon Sep 17 00:00:00 2001 From: "Wu, Jiaxin" <jiaxin.wu@intel.com> Date: Fri, 27 Sep 2019 11:44:38 +0800 Subject: [PATCH 1/8] MdePkg/Include/Protocol/Tls.h: Add the data type of EfiTlsVerifyHost (CVE-2019-14553) REF: https://bugzilla.tianocore.org/show_bug.cgi?id=960 CVE: CVE-2019-14553 In the patch, we add the new data type named "EfiTlsVerifyHost" and the EFI_TLS_VERIFY_HOST_FLAG for the TLS protocol consumer (HTTP) to enable the host name check so as to avoid the potential Man-In-The-Middle attack.

We #define it as a macro. Unfortunately, our macro evaluates the first argument ("str") twice. If the expression passed for "str" has side effects, the behavior may be undefined. In a later patch in this series, we're going to resurrect "inet_pton.c" (originally from the StdLib package), which calls strchr() just like that: strchr((xdigits = xdigits_l), ch) strchr((xdigits = xdigits_u), ch) To enable this kind of function call, turn strchr() into a function.

Note that the other error macro, which we alread #define, namely EINVAL, has a value (22) that also matches "StdLib/Include/errno.h". - The AF_INET and AF_INET6 address family macros come from "StdLib/Include/sys/socket.h". - The NS_INT16SZ, NS_INADDRSZ and NS_IN6ADDRSZ macros come from "StdLib/Include/arpa/nameser.h". - The "u_int" and "u_char" types come from "StdLib/Include/sys/types.h".

Passing the latter to OpenSSL for server certificate validation is important, per RFC-2818 <https://tools.ietf.org/html/rfc2818#section-3.1>: > In some cases, the URI is specified as an IP address rather than a > hostname. In this case, the iPAddress subjectAltName must be present in > the certificate and must exactly match the IP in the URI. Note: we cannot use X509_VERIFY_PARAM_set1_ip_asc() because in the OpenSSL version that is currently consumed by edk2, said function depends on sscanf() for parsing IPv4 literals. In "CryptoPkg/Library/BaseCryptLib/SysCall/CrtWrapper.c", we only provide an empty -- always failing -- stub for sscanf(), however.
