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!

[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. -Ives ____________________________________________________________ Ives Aerts (SW Developer) Sony Telecom Europe ives@sonytel.be St.Stevens Woluwestr. 55 `Death could create most things, B-1130 Brussels, Belgium except for plumbing.'
