patch 9.0.1899: potential buffer overflow in PBYTE macro Commit: https://github.com/vim/vim/commit/ffb13674d1af1c90beb229867ec989e4fb232df3 Author: Christian Brabandt <cb@256bit.org> Date: Fri Sep 15 20:22:02 2023 +0200 patch 9.0.1899: potential buffer overflow in PBYTE macro Problem: potential buffer overflow in PBYTE macro Solution: Check returned memline length closes: #13083 the PBYTE macro is used to put byte c at a position lp of the returned memline. However, in case of unexpected errors ml_get_buf() may return either "???" or an empty line in which case it is quite likely that we are causing a buffer overrun. Therefore, switch the macro PBYTE (which is only used in ops.c anyhow) to a function, that verifies that we will only try to access within the given length of the buffer. Also, since the macro is only used in ops.c, move the definition from macros.h to ops.c Signed-off-by: Christian Brabandt <cb@256bit.org>
