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


Several security issues were fixed in PHP.

Software Description

  • php5 - HTML-embedded scripting language interpreter


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)
