Descriptions
Use after free in utf_ptr2char in GitHub repository vim/vim prior to 8.2.4646.
Un uso de memoria previamente liberada en utf_ptr2char en el repositorio de GitHub vim/vim versiones anteriores a 8.2
A heap use-after-free vulnerability was found in Vim's utf_ptr2char() function of the src/mbyte.c file. This flaw occurs because vim is using a buffer line after it has been freed in the old regexp engine. 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.
