vim: NULL pointer dereference in ex_buffer_all method

CVE-2021-3236 [MEDIUM] CWE-476 vim: NULL pointer dereference in ex_buffer_all method
vim: NULL pointer dereference in ex_buffer_all method
vim 8.2.2348 is affected by null pointer dereference, allows local attackers to cause a denial of service (DoS) via the ex_buffer_all method.
A NULL pointer dereference vulnerability was found in Vim in the ex_buffer_all function in the src/buffer.c file. This flaw allows an attacker who can trick a user into processing a specially crafted file to trigger the NULL pointer dereference, causing the application to crash.
Statement: Red Hat Product Security has rated this issue as having a Low security impact because the user has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it.
