The php_pgsql_meta_data function in pgsql.c in the PostgreSQL (aka pgsql) extension in PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not validate token extraction for table names, which might allow remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted name. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1352.

Security readout for executives and security teams

Older PHP versions with the PostgreSQL extension can crash when handling a specially crafted table name. The documented impact is denial of service, not data theft or code execution. Business urgency depends on whether legacy PHP applications still use the affected pgsql extension and expose table-name handling to remote input. Exposure is most likely in legacy PHP 5.4, 5.5, or 5.6 deployments using the pgsql extension with PostgreSQL-backed application logic. Systems on maintained PHP versions or without the pgsql extension are unlikely to be affected based on the provided sources. Treat this as a legacy-platform availability risk. It is not documented here as code execution or data compromise, but exposed unsupported PHP systems should be prioritized for upgrade because the fix is old and vendor-patched versions have long existed. Mitigation focus: Upgrade PHP to 5.4.42, 5.5.26, 5.6.10, or later supported packages.; Apply relevant vendor security updates from Red Hat, Debian, Gentoo, or Oracle.; Retire unsupported PHP 5.x runtimes where feasible..
