Doc Text:	A heap-based buffer overflow was found in Vim in the ins_compl_add function in the insexpand.c file. This issue occurs due to a read past the end of a buffer when a specially crafted input is processed. This flaw allows an attacker who can trick a user into opening a specially crafted file into triggering the heap-based buffer overflow, causing the application to crash, possibly executing code and corrupting memory.
