    Multiple vulnerabilities have been found in Icedove, Debian's version
    of the Mozilla Thunderbird mail and news client.
    
    CVE-2012-4201
      The evalInSandbox implementation uses an incorrect context during
      the handling of JavaScript code that sets the location.href
      property, which allows remote attackers to conduct cross-site
      scripting (XSS) attacks or read arbitrary files by leveraging a
      sandboxed add-on.
    
    CVE-2012-4207
      The HZ-GB-2312 character-set implementation does not properly handle
      a ~ (tilde) character in proximity to a chunk delimiter, which
      allows remote attackers to conduct cross-site scripting (XSS)
      attacks via a crafted document.
    
    CVE-2012-4216
      Use-after-free vulnerability in the gfxFont::GetFontEntry function
      allows remote attackers to execute arbitrary code or cause a denial
      of service (heap memory corruption) via unspecified vectors.
    
    CVE-2012-5829
      Heap-based buffer overflow in the nsWindow::OnExposeEvent function could
      allow remote attackers to execute arbitrary code.
    
    CVE-2012-5842
      Multiple unspecified vulnerabilities in the browser engine could
      allow remote attackers to cause a denial of service (memory
      corruption and application crash) or possibly execute arbitrary
      code.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 3.0.11-1+squeeze15.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 10.0.11-1.
    
    We recommend that you upgrade your icedove packages.
