 Mandriva Linux Security Advisory                         MDVSA-2013:200
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : ruby
 Date    : July 26, 2013
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been discovered and corrected in ruby:

 The safe-level feature in Ruby 1.8.7 allows context-dependent attackers
 to modify strings via the NameError#to_s method when operating on
 Ruby objects.  NOTE: this issue is due to an incomplete fix for
 CVE-2011-1005 (CVE-2012-4481).

 lib/rexml/text.rb in the REXML parser in Ruby before 1.9.3-p392 allows
 remote attackers to cause a denial of service (memory consumption and
 crash) via crafted text nodes in an XML document, aka an XML Entity
 Expansion (XEE) attack (CVE-2013-1821).

 A flaw was found in Ruby&#039;s SSL client&#039;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 these issues.
