certain multimedia files. If a user were tricked into opening a crafted
multimedia file, an attacker could cause a denial of service via application
crash.
Instructions: In general, a standard system update will make all the necessary changes.

## Abstract
Security advisories are the primary channel of communication for discovered vulnerabilities in open-source software, but they often lack crucial information.
Specifically, 63% of vulnerability database reports are missing their patch links, also referred to as vulnerability fixing commits (VFCs).
This paper introduces VFCFinder, a tool that generates the top-five ranked set of VFCs for a given security advisory using Natural Language Programming Language (NL
