Doc Text:	A global heap buffer overflow vulnerability was found in vim's skip_range() function of the src/ex_docmd.c file. This flaw occurs because vim uses an invalid pointer with "V:" in Ex mode. 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, leading to a denial of service.
