b1147f5faa CVE-2022-23479
Detect attempts to overflow input buffer

If application code hasn't properly sanitised the header_size
for a transport, it is possible for read requests to be issued
which overflow the input buffer. This change detects this
at a low level and bounces the read request.

Remove unnecesssary data from struct auth_info (#2438)
When using PAM authentication, a copy is made of the username and password in the auth_info structure.

The password copy is not cleared from memory when the structure is deallocated. This could mean the password is revealed to an attacker from a coredump.

One solution is to clear the password when the struct is deallocated. However, the username and password in the auth_info struct are only required for the duration of the PAM conversation function. A better solution is to remove the username and password from the auth_info struct entirely, and just use pointers for the duration of the time the callback function is used.

4c8997f033 Fix regression use-after-free
93d97dcb introduced a use-after-free error. The default_font for the
window manager may be used as the font for the main window manager
painter, and so deleting the default_font may cause the painter to
access deallocated memory.

At the point xrdp_wm_init() is called, the only active painter
should be the window manager one.

93d97dcb08 Fix memory leak in font handler
The following sequence of events results in a memory leak as a font
is loaded twice
1) Invoke login screen
2) Try to log in to session, which fails
3) Back to login screen

Fix is to make sure font is deleted before being reloaded.

3279e16bbf Fix freetype2 version checking
The version of freetype2 returned by pkg-config --modversion is
not the same as the product release version. Consequently, the
check for version >= 2.8.0 does not work.

Update pamdir_suse to accommodate with TW pam.d move (#2413)
On newer builds of openSUSE tumbleweed the path of pam.d has moved from
/usr/etc/pam.d to /usr/lib/pam.d, which prevents install script to
correctly guess pam rules. Updating path in mkpamrules solves the
problem.
