Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Ruby Developers report :

There is a vulnerability in DL and Fiddle in Ruby where tainted
strings can be used by system calls regardless of the $SAFE level set
in Ruby.

Native functions exposed to Ruby with DL or Fiddle do not check the
taint values set on the objects passed in. This can result in tainted
objects being accepted as input when a SecurityError exception should
be raised.
