According to [MS-RDPBCGR 2.2.1.3.4.1 Channel Definition Structure]
the channel name must be an 8-byte array containing a null-terminated
collection of seven ANSI characters that uniquely identify the channel.
We did not check if the transmitted name was null-terminated which
could have the usual severe effects on stabiliy and security since
the channel name is used in several functions expecting a null-
terminated string (strlen, printf, etc.)
win32/msvc cc does not recognize the %z format specifier which caused
invalid references and segfaults on win32.
Until FreeRDP gets format specifier macros we'll cast size_t to
unsigned long and use the %lu specifier.
Also simplified winpr_backtrace_symbols() a little bit and fixed it
to allocate the correct amount of bytes for the return buffer.
Details: cbSecurityTrailer was assumed to be a fixed length for all signatures, however for Kerberos authentication the signature may generate smaller than this value
If support for multi layout PDUs is advertised there are known issues
with Windows 7 and Windows 2008R2. Until those are resolved generally
disable multi layout PDUs.
See #3114 for details.
According to [MS-RDPBCGR 2.2.1.11.1.1.1] the TS_EXTENDED_INFO_PACKET
structure's cbClientAddress field must include the _mandatory_ NULL
terminator of the clientAddress field in its byte count.
However, connections proxied via Microsoft's TS Gateway set the
cbClientDir value to 0.
According to [MS-RDPBCGR 2.2.1.11.1.1.1] the TS_EXTENDED_INFO_PACKET
structure's cbClientDir field must include the _mandatory_ NULL
terminator of the ClientDir field.
However, since version 8.1.31.44, the Microsoft Remote Desktop Client
for Android sets cbClientDir to 0.
If a target is linked against libraries with cmake
(target_link_libraries) and the libraries are not marked as PRIVATE
they are "exported" and in case a other target is linked against this
target it is also linked against *all* (not private) libraries.
Without declaring private libraries PRIVATE a lot of over linking
(linking against unneeded libraries) was done.
