iceape - several

Multiple vulnerabilities have been found in Iceape, the Debian Internet suite
based on Mozilla Seamonkey:

• 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.
