The setlocale function in PHP before 5.2.4 allows context-dependent attackers to cause a denial of service (application crash) via a long string in the locale parameter. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless this issue can be demonstrated for code execution.

Security readout for executives and security teams

CVE-2007-4784 is an old PHP denial-of-service issue. PHP before 5.2.4 could crash when setlocale received an overly long locale string. Business impact depends on whether an application lets external users influence locale values passed to PHP. Exposure is likely limited to legacy systems running PHP before 5.2.4 and application paths that pass user-controlled locale input into setlocale. Treat as a legacy-risk cleanup item unless exposed systems still run PHP before 5.2.4. Urgency rises if public-facing applications accept locale input. Mitigation focus: Upgrade PHP systems running versions before 5.2.4.; Check vendor advisories for distribution-specific patched PHP packages.; Restrict accepted locale values to known valid locales..
