Doc Text:
An out-of-bounds write vulnerability was found in Vim's append_command() function of the src/ex_docmd.c file. This issue occurs when an error for a command goes over the end of IObuff. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap buffer overflow that causes an application to crash and corrupt memory.
