when executing spell suggestion commands, which could cause a heap
buffer overflow. An attacker could possibly use this issue to cause a
denial of service or execute arbitrary code. (CVE-2022-0943)

It was discovered that Vim was incorrectly performing bounds checks
when processing invalid commands with composing characters in Ex
mode, which could cause a buffer overflow. An attacker could possibly
use this issue to cause a denial of service or execute arbitrary
code. (CVE-2022-1616)
