patch 9.0.2140: [security]: use-after-free in win-enter
Problem: [security]: use-after-free in win-enter
Solution: validate window pointer before calling win_enter()
win_goto() may stop visual mode, if it is active. However, this may in
turn trigger the ModeChanged autocommand, which could potentially free
the wp pointer which was valid before now became stale and points to now
freed memory.
So before calling win_enter(), let's verify one more time, that the
wp pointer still points to a valid window structure.
Reported by @henices, thanks!

README_ole.txt for version 9.0 of Vim: Vi IMproved. This archive contains gvim.exe with OLE interface. This version of gvim.exe can also load a number of interface dynamically (you can optionally install the .dll files for each interface). It is only for MS-Windows 95/98/ME/NT/2000/XP. Also see the README_bindos.txt, README_dos.txt and README.txt files. Be careful not to overwrite the OLE gvim.exe with the non-OLE gvim.exe when unpacking another binary archive! Check the output of ":version": Win32s - "MS-Windows 16/32 bit GUI version" Win32 - "MS-Windows 32 bit GUI version" Win32 with OLE - "MS-Windows 32 bit GUI version with OLE support" For further information, type this inside Vim: :help if_ole
