Package : php7.4 Version : 7.4.33-1+deb11u9 CVE ID : CVE-2025-1220 CVE-2025-1735 CVE-2025-6491

Multiple security issues were found in PHP, a widely-used open source general purpose scripting language, which could result in server side request forgery or denial of service.

CVE-2025-1220

Jihwan Kim discovered that fsockopen() lack validation that the 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.

This issue is related to CVE-2025-1094 which was reported to PostgreSQL.

CVE-2025-6491

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.

For Debian 11 bullseye, these problems have been fixed in version 7.4.33-1+deb11u9.

We recommend that you upgrade your php7.4 packages.
