[slackware-security] ruby (SSA:2017-353-01)

New ruby packages are available for Slackware 14.2 and -current to
fix a security issue.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/ruby-2.2.9-i586-1_slack14.2.txz: Upgraded.
This update fixes a security issue:
Net::FTP#get, getbinaryfile, gettextfile, put, putbinaryfile, and puttextfile
use Kernel#open to open a local file. If the localfile argument starts with
the pipe character "|", the command following the pipe character is
executed.
The default value of localfile is File.basename(remotefile), so malicious FTP
servers could cause arbitrary command execution.
For more information, see:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-17405
(* Security fix *)
+--------------------------+
