CVE-2022-1160

A heap buffer overflow flaw was found in vim’s get_one_sourceline() function of scriptfile.c file. This flaw occurs when “source” can read past the end of the copied line. This flaw allows an attacker to trick a user into opening a crafted file, triggering a heap-overflow and causing an application to crash, which leads to a denial of service.

Mitigation

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