Detailsinfo

A vulnerability was found in PHP up to 8.1.33/8.2.29/8.3.28/8.4.15/8.5.0 and classified as problematic. Affected by this issue is the function pdo_parse_params of the component PDO PostgreSQL Driver. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-14180 since 12/06/2025. The exploitation is known to be difficult. The attack may be launched remotely.
