patch 9.0.2129: [security]: use-after-free in call_dfunc()
Problem: [security]: use-after-free in call_dfunc()
Solution: Refresh dfunc pointer
closes: #13571
This Commit fixes a SEGV caused by a use-after-free bug in call_dfunc().
When calling check_ufunc_arg_types() from the call_dfunc() it may cause
def functions to be re-compiled and if there are too many def functions,
the def_functions array will be re-allocated. Which means, that the
dfunc pointer in call_dfunc() now starts pointing to freed memory.
So we need to reset the dfunc pointer after calling
check_ufunc_arg_types().
Let's also add a test, to ensure we do not regress.

[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.'
