De Eindbazen discovered that PHP, when run with mod_cgi, will interpret a query string as command line parameters, allowing to execute arbitrary code. Additionally, this update fixes insufficient validation of upload name which lead to corrupted $_FILES indices. For the stable distribution (squeeze), this problem has been fixed in version 5.3.3-7+squeeze9. The testing distribution (wheezy) will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 5.4.3-1. We recommend that you upgrade your php5 packages.
