hostname supplied does not contain null characters, which may lead
to other functions like parse_url() to treat the hostname in an
incorrect way, thereby potentially causing Server Side Request
Forgery.

CVE-2025-1735

It was discovered that pgsql and pdo_pgsql escaping functions do not
check if the underlying quoting functions returned errors, which may
lead to crashes due to null pointer dereferences.

PostgreSQL.

Ahmed Lekssays discovered that SoapVar instances created with a
fully qualified name larger than 2G could lead to denial of service
due to null pointer dereference.
