"It was discovered that PHP incorrectly handled certain character
sequences when applying HTTP response-splitting protection. A remote
attacker could create a specially crafted URL and inject arbitrary
headers. (CVE-2011-1398, CVE-2012-4388)

It was discovered that PHP incorrectly handled directories with a
large number of files. This could allow a remote attacker to execute
arbitrary code with the privileges of the web server, or to perform a
denial of service. (CVE-2012-2688)

It was discovered that PHP incorrectly parsed certain PDO prepared
statements. A remote attacker could use this flaw to cause PHP to
crash, leading to a denial of service. (CVE-2012-3450).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
