Several security related problems have been found in PHP4, the server-side, HTML-embedded scripting language. The Common Vulnerabilities and Exposures project identifies the following problems:
Eric Romang discovered insecure temporary files in the shtool utility shipped with PHP that can exploited by a local attacker to overwrite arbitrary files. Only this vulnerability affects packages in oldstable.
GulfTech has discovered that PEAR XML_RPC is vulnerable to a remote PHP code execution vulnerability that may allow an attacker to compromise a vulnerable server.
Stefan Esser discovered another vulnerability in the XML-RPC libraries that allows injection of arbitrary PHP code into eval() statements.
For the old stable distribution (woody) these problems have been fixed in version 4.1.2-7.woody5.
For the stable distribution (sarge) these problems have been fixed in version 4.3.10-16.
For the unstable distribution (sid) these problems have been fixed in version 4.4.0-2.
We recommend that you upgrade your PHP packages.
