Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2025-14180)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within PDO implementation. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


2) Heap-based buffer overflow (CVE-ID: CVE-2025-14178)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the array_merge() PPH function. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Memory leak (CVE-ID: CVE-2025-14177)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in getimagesize. A remote attacker can force the application to leak memory and perform denial of service attack.


4) Uncontrolled recursion (CVE-ID: CVE-2025-67899)

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to uncontrolled recursion in uriparser. A remote attacker can pass specially crafted input to the application and perform a denial of service attack. 


5) Input validation error (CVE-ID: N/A)

The vulnerability allows a remote attacker to tamper with application workflow.

The vulnerability exists due to insufficient validation of user-supplied input in dns_get_record() and other DNS functions. A remote attacker can pass specially crafted input with a NULL byte character to the application and tamper with application;s workflow, potentially performing SSRF attack.
