CVE-2006-1490: PHP before 5.1.3-RC1 might allow remote attackers to obtain portions of memory via crafted binary data sent...

Security readout for executives and security teams

This is an old PHP information-disclosure flaw. Certain PHP versions before 5.1.3-RC1 could return fragments of server memory when vulnerable scripts processed attacker-supplied binary input through html_entity_decode and reflected results to the client. Exposure is most likely in legacy PHP deployments running versions before 5.1.3-RC1 or older vendor-packaged PHP builds, especially public scripts that decode and reflect user-controlled input. Prioritize this where legacy PHP systems still handle sensitive data. Modern supported PHP should not be affected, but old internet-facing applications can create confidentiality risk even without authentication bypass or code execution. Mitigation focus: Upgrade PHP using the relevant vendor advisory or fixed upstream release guidance.; Inventory any PHP runtime older than 5.1.3-RC1 or equivalent vendor backport.; Review public scripts that call html_entity_decode on user-controlled input..
