    Summary:
    
    Several security issues were fixed in PHP.
    
    Software Description:

    Details:
    
    USN-3600-1 fixed a vulnerability in PHP. This update provides
    the corresponding update for Ubuntu 12.04 ESM.
    
    Original advisory details:
    
     It was discovered that PHP incorrectly handled the PHAR 404 error
     page. A remote attacker could possibly use this issue to conduct
     cross-site scripting (XSS) attacks. (CVE-2018-5712)
    
     It was discovered that PHP incorrectly handled parsing certain HTTP
     responses. A remote attacker could use this issue to cause PHP to
     crash, resulting in a denial of service, or possibly execute arbitrary
     code. (CVE-2018-7584)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 ESM:
      libapache2-mod-php5             5.3.10-1ubuntu3.30
      php5                            5.3.10-1ubuntu3.30
      php5-cgi                        5.3.10-1ubuntu3.30
      php5-cli                        5.3.10-1ubuntu3.30
      php5-fpm                        5.3.10-1ubuntu3.30
    
    In general, a standard system update will make all the necessary
    changes.
