https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D200979 Bug ID: 200979 Summary: security/vuxml: document devel/rubygem-paperclip security announcement on spoofing issue Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: jason.unovitch@gmail.com CC: ports-secteam@FreeBSD.org, ruby@FreeBSD.org CC: ports-secteam@FreeBSD.org, ruby@FreeBSD.org Created attachment 157891 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D157891&action= =3Dedit 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."
