PHP is an HTML-embedded scripting language commonly used with the
Apache HTTP Server.

It was discovered that the fix for CVE-2011-4885 (released via

Red Hat Enterprise Linux 4, 5, and 6 respectively) introduced an
uninitialized memory use flaw. A remote attacker could send a
specially crafted HTTP request to cause the PHP interpreter to crash
or, possibly, execute arbitrary code. (CVE-2012-0830)

All php users should upgrade to these updated packages, which contain
a backported patch to resolve this issue. After installing the updated
packages, the httpd daemon must be restarted for the update to take
