[SECURITY] [DLA 1222-1] ruby1.8 security update

Package : ruby1.8
Version : 1.8.7.358-7.1+deb7u5
CVE ID : CVE-2017-17405 CVE-2017-17790

Several vulnerabilities have been discovered in the interpreter for the
Ruby language. The Common Vulnerabilities and Exposures project
identifies the following problems:

CVE-2017-17405

A command injection vulnerability in Net::FTP might allow a
malicious FTP server the execution of arbitrary commands.

CVE-2017-17790

A command injection vulnerability in lib/resolv.rb's lazy_initialze
might allow a command injection attack. However untrusted input to
this function is rather unlikely.

For Debian 7 "Wheezy", these problems have been fixed in version
1.8.7.358-7.1+deb7u5.

We recommend that you upgrade your ruby1.8 packages.
