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...

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.

Security readout for executives and security teams

This is an old PHP memory-safety issue in the printf-style formatting functions. On 64-bit systems running PHP 4 before 4.4.5 or PHP 5 before 5.2.1, certain formatting inputs could allow arbitrary code execution depending on application context. Exposure is most likely in legacy 64-bit servers still running PHP 4.x before 4.4.5 or PHP 5.x before 5.2.1, especially where application code passes attacker-influenced values into PHP printf-style formatting functions. Prioritize remediation for any internet-facing or business-critical legacy PHP systems. The issue is old, but arbitrary code execution impact and unsupported runtimes make remaining exposure a serious operational risk. Mitigation focus: Inventory 64-bit systems running PHP 4.x or early PHP 5.x.; Upgrade affected PHP runtimes to fixed or currently supported versions.; Review OS or appliance vendor advisories for packaged PHP fixes..
