Doc Text:
A use-after-free vulnerability was found in Vim in the skipwhite function in the charset.c file. This issue occurs because an already freed memory is used when a specially crafted input is processed. This flaw allows an attacker who can trick a user into opening a specially crafted file into triggering the use-after-free, and cause the application to crash, possibly executing code and corrupting memory.
