    php5 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 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 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)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      php5                            5.3.10-1ubuntu3.4
    
    Ubuntu 11.10:
      php5                            5.3.6-13ubuntu3.9
    
    Ubuntu 11.04:
      php5                            5.3.5-1ubuntu7.11
    
    Ubuntu 10.04 LTS:
      php5                            5.3.2-1ubuntu4.18
    
    Ubuntu 8.04 LTS:
      php5                            5.2.4-2ubuntu5.26
    
    In general, a standard system update will make all the necessary changes.
