Doc Text:
A heap buffer over-read vulnerability was found in Vim's grab_file_name() function of the src/findfile.c file. This flaw occurs because the function reads after the NULL terminates the line with "gf" in Visual block mode. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap buffer over-read vulnerability that causes an application to crash and corrupt memory.
