Doc Text:	A heap buffer over-read vulnerability was found in Vim's put_on_cmdline() function of the src/ex_getln.c file. This issue occurs due to invalid memory access when using an expression on the command line. 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.	Story Points:	---
