TITLE: Remote command Injection in Creme Fraiche 0.6 Ruby Gem

DATE: 5/14/2013

AUTHOR: Larry W. Cashdollar (@_larry0)

DOWNLOAD: http://rubygems.org/gems/cremefraiche, http://www.uplawski.eu/technology/cremefraiche/

DESCRIPTION: Converts Email to PDF files.

VENDOR: Notifed on 5/13/2013, provided fix 5/14/2013

FIX: Version in 0.6.1

CVE: 2013-2090

DETAILS: The following lines pass unsanitized user input directly to the command line.
A malicious email attachment with a file name consisting of shell meta characters could inject commands into the shell.

If the attacker is allowed to specify a filename (via a web gui) commands could be injected that way as well.
