Vulnerability Details : CVE-2007-1884
Multiple integer signedness errors in the printf function family in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 on 64 bit machines allow context-dependent attackers to execute arbitrary code via (1) certain negative argument numbers that arise in the php_formatted_print function because of 64 to 32 bit truncation, and bypass a check for the maximum allowable value; and (2) a width and precision of -1, which make it possible for the php_sprintf_appendstring function to place an internal buffer at an arbitrary memory location.

Vendor statements for CVE-2007-1884
-
Red Hat 2007-04-16The PHP interpreter does not offer a reliable "sandboxed" security layer (as found in, say, a JVM) in which untrusted scripts can be run; any script run by the PHP interpreter must be trusted with the privileges of the interpreter itself. We therefore do not classify this issue as security-sensitive since no trust boundary is crossed.
