tag_insight = "USN 1358-1 fixed multiple vulnerabilities in PHP. The fix for
  CVE-2012-0831 introduced a regression where the state of the
  magic_quotes_gpc setting was not correctly reflected when calling
  the ini_get() function.

  We apologize for the inconvenience.

  Original advisory details:

  It was discovered that PHP computed hash values for form parameters
  without restricting the ability to trigger hash collisions predictably.
  This could allow a remote attacker to cause a denial of service by
  sending many crafted parameters. (CVE-2011-4885)

  ATTENTION: this update changes previous PHP behavior by
  limiting the number of external input variables to 1000.
  This may be increased by adding a "max_input_vars"
  directive to the php.ini configuration file. See
  http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars
  for more information.

  Stefan Esser discovered that the fix to address the predictable hash
  collision issue, CVE-2011-4885, did not properly handle the situation
  where the limit was reached. This could allow a remote attacker to
  cause a denial of service or execute arbitrary code via a request
  containing a large number of variables. (CVE-2012-0830)

  It was discovered that PHP did not always check the return value of
  the zend_strndup function. This could allow a remote attacker to
  cause a denial of service. (CVE-2011-4153)

  It was discovered that PHP did not properly enforce libxslt security
  settings. This could allow a remote attacker to create arbitrary
  files via a crafted XSLT stylesheet that uses the libxslt output
  extension. (CVE-2012-0057)

  It was discovered that PHP did not properly enforce that PDORow
  objects could not be serialized and not be saved in a session. A
  remote attacker could use this to cause a denial of service via an
  application crash. (CVE-2012-0788)

  It was discovered that PHP allowed the magic_quotes_gpc setting to
  be disabled remotely. This could allow a remote attacker to bypass
  restrictions that could prevent an SQL injection. (CVE-2012-0831)

  USN 1126-1 addressed an issue where the /etc/cron.d/php5 cron job
  for PHP allowed local users to delete arbitrary files via a symlink
  attack on a directory under /var/lib/php5/. Emese Revfy discovered
  that the fix had not been applied to PHP for Ubuntu 10.04 LTS. This
  update corrects the issue. We apologize for the error. (CVE-2011-0441)";
