CVE-2008-1384 Integer overflow allows context-dependent attackers to cause a denial of service and possibly have other impact via a printf format parameter with a large width specifier. CVE-2008-2050 Stack-based buffer overflow in the FastCGI SAPI. CVE-2008-2051 The escapeshellcmd API function could be attacked via incomplete multibyte chars. This update als includes a fix which was pending for the next Debian 4.0 `etch' stable update, for crashes in php5-recode (Debian bug 459020).
