CVE-2022-1381

A global heap buffer overflow vulnerability was found in vim's skip_range() function of the src/ex_docmd.c file. This flaw occurs because vim uses an invalid pointer with "V:" in Ex mode. 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, leading to a denial of service.

The versions of Vim shipped with Red Hat Enterprise Linux are not affected, because there is no presence of vulnerable code in our code-base.

Red Hat Enterprise Virtualization 4 consumes RHEL-8 vim, and as RHEL-8 is not affected, Hence, RHEV is also not affected.
