Original advisory details:

 It was discovered that PHP did not sanitize certain error messages when
 display_errors is enabled, which could result in browsers becoming
 vulnerable to cross-site scripting attacks when processing the output.
 With cross-site scripting vulnerabilities, if a user were tricked into
 viewing server output during a crafted server request, a remote attacker
 could exploit this to modify the contents, or steal confidential data
 (such as passwords), within the same domain. (CVE-2008-5814)

 It was discovered that PHP did not properly handle certain malformed
 strings when being parsed by the json_decode function. A remote attacker
 could exploit this flaw and cause the PHP server to crash, resulting in a
 denial of service. This issue only affected Ubuntu 8.04 and 8.10.
 (CVE-2009-1271)");
