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.
