    Several vulnerabilities have been discovered in Icedove, a mail client
    based on Thunderbird.
    
    CVE-2011-3647
            The JSSubScriptLoader does not properly handle
            XPCNativeWrappers during calls to the loadSubScript method in
            an add-on, which makes it easier for remote attackers to gain
            privileges via a crafted web site that leverages certain
            unwrapping behavior.
    
    CVE-2011-3648
    	A cross-site scripting (XSS) vulnerability allows remote
    	attackers to inject arbitrary web script or HTML via crafted
    	text with Shift JIS encoding.
    
    CVE-2011-3650 
            Iceweasel does not properly handle JavaScript files that
    	contain many functions, which allows user-assisted remote
    	attackers to cause a denial of service (memory corruption and
    	application crash) or possibly have unspecified other impact
    	via a crafted file that is accessed by debugging APIs, as
    	demonstrated by Firebug.
    
    For the stable distribution (squeeze), these problems have been fixed
    in version 3.0.11-1+squeeze6.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), these problems have been fixed in version 3.1.15-1.
    
    We recommend that you upgrade your icedove packages.
