Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Memory leak (CVE-ID: CVE-2021-41687)

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

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


2) Double Free (CVE-ID: CVE-2021-41688)

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

The vulnerability exists due to a boundary error. A remote attacker can pass specially crafted data to the application, trigger a double free error and perform a denial of service (DoS) attack.


3) NULL pointer dereference (CVE-ID: CVE-2021-41689)

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

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


4) Memory leak (CVE-ID: CVE-2021-41690)

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

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


5) Path traversal (CVE-ID: CVE-2022-2119)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the service class provider (SCP). A remote attacker on the local network can send a specially crafted HTTP request and write arbitrary files on the system, leading to remote code execution.


6) Path traversal (CVE-ID: CVE-2022-2120)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the service class user (SCU). A remote attacker can send a specially crafted HTTP request and write arbitrary files on the system, leading to remote code execution.


7) NULL pointer dereference (CVE-ID: CVE-2022-2121)

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

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


8) Memory leak (CVE-ID: CVE-2022-43272)

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

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