  the program. (CVE-2011-0216)

  It was discovered that libxml2 is vulnerable to double-free conditions
  when parsing certain XML documents. This could allow a remote attacker to
  cause a denial of service. (CVE-2011-2821, CVE-2011-2834)

  It was discovered that libxml2 did not properly detect end of file when
  parsing certain XML documents. An attacker could exploit this to crash
  applications linked against libxml2. (CVE-2011-3905)

  It was discovered that libxml2 did not properly decode entity references
  with long names. If a user or application linked against libxml2 were
  tricked into opening a specially crafted XML file, an attacker could cause
