A security issue affects these releases of Ubuntu and its derivatives:

Summary:

Vim could be made to crash if it received specially crafted input.

Software Description:

Details:

buffer, leading to use-after-free. If a user was tricked into opening a
specially crafted file, an attacker could crash the application, leading to
a denial of service.
