CVE-2022-0714

A heap-buffer-overflow flaw was found in vim’s win_lbr_chartabsize() function of charset.c file. The issue occurs due to an incorrect ‘vartabstop’ value. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap-overflow, and can cause an application to crash, eventually leading to a denial of service.

Mitigation

Untrusted vim scripts with -s [scriptin] are not recommended to run.
