 Mandriva Linux Security Advisory                         MDVSA-2008:226
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : ruby
 Date    : November 6, 2008
 Affected: 2008.0, 2008.1, Corporate 3.0, Corporate 4.0
 _______________________________________________________________________

 Problem Description:

 A denial of service condition was found in Ruby's regular expression
 engine.  If a Ruby script tried to process a large amount of data
 via a regular expression, it could cause Ruby to enter an infinite
 loop and crash (CVE-2008-3443).
 
 A number of flaws were found in Ruby that could allow an attacker to
 create a carefully crafted script that could allow for the bypass of
 certain safe-level restrictions (CVE-2008-3655).
 
 A denial of service vulnerability was found in Ruby's HTTP server
 toolkit, WEBrick.  A remote attacker could send a specially-crafted
 HTTP request to a WEBrick server that would cause it to use an
 excessive amount of CPU time (CVE-2008-3656).
 
 An insufficient taintness check issue was found in Ruby's DL module,
 a module that provides direct access to the C language functions.
 This flaw could be used by an attacker to bypass intended safe-level
 restrictions by calling external C functions with the arguments from
 an untrusted tainted input (CVE-2008-3657).
 
 A denial of service condition in Ruby's XML document parsing module
 (REXML) could cause a Ruby application using the REXML module to use
 an excessive amount of CPU and memory via XML documents with large
 XML entitity definitions recursion (CVE-2008-3790).
 
 The Ruby DNS resolver library used predictable transaction IDs and
 a fixed source port when sending DNS requests.  This could be used
 by a remote attacker to spoof a malicious reply to a DNS query
 (CVE-2008-3905).
 
 The updated packages have been patched to correct these issues.
