    Package : icedove
    Vulnerability : several
    Problem type : local (remote)
    Debian-specific: no
    CVE ID : CVE-2011-3647 CVE-2011-3648 CVE-2011-3650

    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.
