==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04

- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in PHP.

Software Description:
- php5: HTML-embedded scripting language interpreter

Details:

It was discovered that PHP incorrectly handled the xml_parse_into_struct
function. If a PHP application parsed untrusted XML, an attacker could use
this flaw with a specially-crafted XML document to cause PHP to crash,
resulting in a denial of service, or to possibly execute arbitrary code.
(CVE-2013-4113)

It was discovered that PHP incorrectly handled the jdtojewish function. An
attacker could use this flaw to cause PHP to crash, resulting in a denial
of service. (CVE-2013-4635)
