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)";
