Oracle Linux: CVE-2025-14180: ELSA-2026-1409: php:8.2 security update (IMPORTANT) (Multiple Advisories)

In PHP versions 8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1 when using the PDO PostgreSQL driver with PDO::ATTR_EMULATE_PREPARES enabled, an invalid character sequence (such as \x99) in a prepared statement parameter may cause the quoting function PQescapeStringConn to return NULL, leading to a null pointer dereference in pdo_parse_params() function. This may lead to crashes (segmentation fault) and affect the availability of the target server.
A flaw was found in PHP. When the PDO (PHP Data Objects) PostgreSQL driver is configured with `PDO::ATTR_EMULATE_PREPARES` enabled, a remote attacker can exploit a vulnerability by providing an invalid character sequence within a prepared statement parameter. This can cause a null pointer dereference, leading to a server crash. The primary impact is a Denial of Service (DoS), affecting the availability of the target server.
