Debian Bug : 479723

Several vulnerabilities have been discovered in PHP, a server-side,
HTML-embedded scripting language. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2007-3806

    The glob function allows context-dependent attackers to cause
    a denial of service and possibly execute arbitrary code via
    an invalid value of the flags parameter.

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).

For the stable distribution (etch), these problems have been fixed in
version 5.2.0-8+etch11.

For the unstable distribution (sid), these problems have been fixed in
version 5.2.6-1.

We recommend that you upgrade your php5 package.
