Several vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language. The Common Vulnerabilities and Exposures project identifies the following problems:
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.
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.
Stack-based buffer overflow in the FastCGI SAPI.
The escapeshellcmd API function could be attacked via incomplete multibyte chars.
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.
