Doc Text:
A NULL pointer dereference vulnerability was discovered in vim's utfc_ptr2len() function in the mbyte.c file. This issue is due to using a NULL pointer with the nested :open command. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering an issue that causes an application to crash, leading to a denial of service.
