A flaw was found in Ruby's SSL client's hostname identity check when
handling certificates that contain hostnames with NULL bytes. An
attacker could potentially exploit this flaw to conduct
man-in-the-middle attacks to spoof SSL servers. Note that to exploit
this issue, an attacker would need to obtain a carefully-crafted
certificate signed by an authority that the client trusts
(CVE-2013-4073).

The updated packages have been patched to correct this issue."
