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
RHSA-2012:0019 for php53 packages in Red Hat Enterprise Linux 5)
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 php53 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 effect.
