Doc Text:
A heap use-after-free vulnerability was found in vim's do_tag() function of the src/tag.c file. The issue triggers when the 'tagfunc' closes the window. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap use-after-free that causes an application to crash, possibly executing code and corrupting memory.
