OVERVIEW

        WordPress 3.3.2 is now available which resolves 3 external library 
        security issues, along with 3 other security issues. [1]


IMPACT

        The three external library issues fixed in WordPress 3.3.2 include:
        
        "Unspecified vulnerability in wp-includes/js/swfupload/swfupload.swf 
        in WordPress before 3.3.2 has unknown impact and attack vectors." [2]
        
        "Unspecified vulnerability in wp-includes/js/swfobject.js in 
        WordPress before 3.3.2 has unknown impact and attack vectors." [3]
        
        "Plupload before 1.5.4, as used in wp-includes/js/plupload/ in 
        WordPress before 3.3.2 and other products, enables scripting 
        regardless of the domain from which the SWF content was loaded, 
        which allows remote attackers to bypass the Same Origin Policy via 
        crafted content." [4]
        
        Limited privilege escalation and cross-site scripting 
        vulnerabilities were also fixed. [1]


MITIGATION

        The vendor recommends upgrading to WordPress WordPress 3.3.2. [1]
