    Debian Bug     : 
    
    Multiple vulnerabilities have been found in Iceweasel, the Debian web browser
    based on Mozilla Firefox:
    
    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.
    
    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-2012-4201
    
      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-2012-4216
    
      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.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 3.5.16-20.
    
    For the testing distribution (wheezy), these problems have been fixed in
    version 10.0.11esr-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 10.0.11esr-1.
    
    We recommend that you upgrade your iceweasel packages.
