Title: PHP Printf() Function 64bit Casting Multiple Format String Vulnerabilities

Severity: HIGH

Description:

PHP is a general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

PHP is prone to multiple format-string vulnerabilities due to a design error when casting 64-bit variables to 32 bits.

Specifically, the vulnerabilities reside in the 'php_sprintf_getnumber()' and 'php_sprintf_appendstring()' helper functions of the 'printf()' function family. The first helper function extracts the argument number, width, or precision for the 'php_formatted_print()' function. On 64-bit systems, these helper functions return an unsigned 63-bit long variable that is truncated and stored in 32-bit format. Because the calling code ensures that numbers must always be long positive numbers, when truncated they may become negative numbers, which are unexpected. This may cause the application to behave incorrectly, referencing arbitrary memory addresses or to overwrite heap control structures. Attackers may exploit the later condition to overwrite heap control structures with characters in the format string to execute arbitrary code.

Attackers may be able to exploit these issues to execute arbitrary code in the context of the webserver process or to cause denial-of-service conditions.

These issues affect PHP versions prior to 4.4.5 and 5.2.1 running on 64-bit computers.
