patch 9.0.2143: [security]: buffer-overflow in ex_substitute Commit: https://github.com/vim/vim/commit/abfa13ebe92d81aaf66669c428d767847b577453 Author: Christian Brabandt <cb@256bit.org> Date: Thu Nov 30 11:32:18 2023 +0100 patch 9.0.2143: [security]: buffer-overflow in ex_substitute Problem: [security]: buffer-overflow in ex_substitute Solution: clear memory after allocating When allocating the new_start pointer in ex_substitute() the memory pointer points to some garbage that the following for loop in ex_cmds.c:4743 confuses and causes it to accessing the new_start pointer beyond it's size, leading to a buffer-overlow. So fix this by using alloc_clear() instead of alloc(), which will clear the memory by NUL and therefore cause the loop to terminate correctly. Reported by @henices, thanks! closes: #13596 Signed-off-by: Christian Brabandt <cb@256bit.org>

README_vms.txt for version 9.0 of Vim: Vi IMproved.

This file explains the installation of Vim on VMS systems.
See "README.txt" in the runtime archive for information about Vim.


Most information can be found in the on-line documentation.  Use ":help vms"
inside Vim.  Or get the runtime files and read runtime/doc/os_vms.txt to find
out how to install and configure Vim with runtime files etc.

To compile Vim yourself you need three archives:
  vim-X.X-rt.tar.gz	runtime files
  vim-X.X-src.tar.gz	source files
  vim-X.X-extra.tar.gz	extra source files

Compilation is recommended, in order to make sure that the correct
libraries are used for your specific system.  Read about compiling in
src/INSTALLvms.txt.

To use the binary version, you need one of these archives:

  vim-XX-exe-ia64-gui.zip       IA64 GUI/Motif executables
  vim-XX-exe-ia64-gtk.zip       IA64 GUI/GTK executables
  vim-XX-exe-ia64-term.zip      IA64 console executables
  vim-XX-exe-axp-gui.zip	Alpha GUI/Motif executables
  vim-XX-exe-axp-gtk.zip	Alpha GUI/GTK executables
  vim-XX-exe-axp-term.zip       Alpha console executables
  vim-XX-exe-vax-gui.zip	VAX GUI executables
  vim-XX-exe-vax-term.zip       VAX console executables

and of course
  vim-XX-runtime.zip		runtime files

The binary archives contain: vim.exe, ctags.exe, xxd.exe files,
but there are also prepared "deploy ready" archives:

vim-XX-ia64.zip			GUI and console executables with runtime and
				help files for IA64 systems
vim-XX-axp.zip			GUI and console executables with runtime and
				help files for Alpha systems
vim-XX-vax.zip			GUI and console executables with runtime and
				help files for VAX systems

GTK builds need LIBGTK library installed.

These executables and up to date patches for OpenVMS system are downloadable
from http://www.polarhome.com/vim/ or ftp://ftp.polarhome.com/pub/vim/
