patch 9.0.2158: [security]: use-after-free in check_argument_type
Problem: [security]: use-after-free in check_argument_type
Solution: Reset function type pointer when freeing the function type
list
function pointer fp->uf_func_type may point to the same memory, that was
allocated for fp->uf_type_list. However, when cleaning up a function
definition (e.g. because it was invalid), fp->uf_type_list will be
freed, but fp->uf_func_type may still point to the same (now) invalid
memory address.
So when freeing the fp->uf_type_list, check if fp->func_type points to
any of those types and if it does, reset the fp->uf_func_type pointer to
the t_func_any (default) type pointer
closes: #13652

README_ami.txt for version 9.0 of Vim: Vi IMproved. This file explains the installation of Vim on Amiga systems. See README.txt for general information about Vim. Unpack the distributed files in the place where you want to keep them. It is wise to have a "vim" directory to keep your vimrc file and any other files you change. The distributed files go into a subdirectory. This way you can easily upgrade to a new version. For example: dh0:editors/vim contains your vimrc and modified files dh0:editors/vim/vim54 contains the Vim version 5.4 distributed files dh0:editors/vim/vim55 contains the Vim version 5.5 distributed files You would then unpack the archives like this: cd dh0:editors tar xf t:vim90bin.tar tar xf t:vim90rt.tar Set the $VIM environment variable to point to the top directory of your Vim files. For the above example: set VIM=dh0:editors/vim Vim version 5.4 will look for your vimrc file in $VIM, and for the runtime files in $VIM/vim54. See ":help $VIM" for more information. Make sure the Vim executable is in your search path. Either copy the Vim executable to a directory that is in your search path, or (preferred) modify the search path to include the directory where the Vim executable is.
