Details

USN-761-1 fixed vulnerabilities in PHP.
This update provides the corresponding updates for Ubuntu 9.04.

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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04

In general, a standard system upgrade is sufficient to effect the
necessary changes.
