patch 9.0.2142: [security]: stack-buffer-overflow in option callback functions Commit: https://github.com/vim/vim/commit/b39b240c386a5a29241415541f1c99e2e6b8ce47 Author: Christian Brabandt <cb@256bit.org> Date: Wed Nov 29 11:34:05 2023 +0100 patch 9.0.2142: [security]: stack-buffer-overflow in option callback functions Problem: [security]: stack-buffer-overflow in option callback functions Solution: pass size of errbuf down the call stack, use snprintf() instead of sprintf() We pass the error buffer down to the option callback functions, but in some parts of the code, we simply use sprintf(buf) to write into the error buffer, which can overflow. So let's pass down the length of the error buffer and use sprintf(buf, size) instead. Reported by @henices, thanks! Signed-off-by: Christian Brabandt <cb@256bit.org>
