CVE-2022-2000

An out-of-bounds write vulnerability was found in Vim's append_command() function of the src/ex_docmd.c file. This issue occurs when an error for a command goes over the end of IObuff. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap buffer overflow that causes an application to crash and corrupt memory.

All versions of Vim shipped with Red Hat Enterprise Linux are not affected, because vulnerable code is not present in our code-base.

Red Hat Product Security has rated this issue as having a Low security impact because the "victim" 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.
