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.

[adopted from a message that Ives posted in the Vim mailing list]

Some compilers produce an error message that cannot be handled with
'errorformat' in Vim.  Following is an example of a Perl script that
translates one error message into something that Vim understands.


The compiler that generates this kind of error messages (4 lines):

"/tmp_mnt/cm/src/apertos/MoU/MetaCore/MetaCore/common/src/MetaCoreImp_M.cc",
line 50: error(3114):
	   identifier "PRIMITIVE_M" is undefined
	 return(ExecuteCore(PRIMITIVE_M,

You can find a small perl program at the end.
The way I use it is:

:set   errorformat=%f>%l:%c:%t:%n:%m
:set   makeprg=clearmake\ -C\ gnu
:set   shellpipe=2>&1\|\ vimccparse

If somebody thinks this is useful: feel free to do whatever you can think
of with this code.
