  script_tag(name:"insight", value:"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
 [link moved to references]
 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)");
