Document devel/rubygem-papercut security advisory

JVN.jp documents this as CVE-2015-2963

Source: https://robots.thoughtbot.com/paperclip-security-release
"We just released paperclip v4.2.2. This contains only a security patch over
v4.2.1, and everyone is encouraged to upgrade. The commit message explains =
the
problem and fix:

There is an issue where if an HTML file is uploaded with a .html extension,=
 but
the content type is listed as being image/jpeg, this will bypass a validati=
on
checking for images. But it will also pass the spoof check, because a file
named .html and containing actual HTML passes the spoof check.

This change makes it so that we also check the supplied content type. So ev=
en
if the file contains HTML and ends with .html, it doesn=E2=80=99t match the=
 content
type of image/jpeg and so it fails.

This vulnerability was assigned JVN #83881261.

paperclip is a Rubygem that that lets you attach files to ActiveRecord mode=
ls.

Thanks to Jon Yurek and Mike Burns for their work on this, and special than=
ks
to MORI Shingo of DeNA Co., Ltd. for reporting the vulnerability."
