Subject: CVE request: DoS vulnerability in Ruby gem Paperclip


I believe there's a denial of service vulnerability in Paperclip version
4.2.2 through 4.3.5: it's possible to cause a DoS by uploading files with a
spoofed media type, because it causes megabytes of logging (data from the
mime-types gem) to be written. See for more information.

It seems to be introduced in this commit
version 4.2.2 and it's fixed in 4.3.6 (released yesterday) with this pull
