Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Code Injection (CVE-ID: CVE-2020-13936)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation. A remote attacker with ability to modify Velocity templates can inject and execute arbitrary Java code on the system with the same privileges as the account running the Servlet container.
2) Resource exhaustion (CVE-ID: CVE-2022-25857)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when handling YAML files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Stack-based buffer overflow (CVE-ID: CVE-2022-38749)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when handling YAML files. A remote attacker can pass a specially crafted YAML file to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.4) Stack-based buffer overflow (CVE-ID: CVE-2022-38750)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when handling YAML files. A remote attacker can pass a specially crafted YAML file to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.5) Out-of-bounds write (CVE-ID: CVE-2022-38751)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing untrusted YAML input. A remote attacker can pass a specially crafted YAML file to the application, trigger out-of-bounds write and perform a denial of service (DoS) attack.
6) Stack-based buffer overflow (CVE-ID: CVE-2022-38752)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when handling YAML files. A remote attacker can pass a specially crafted YAML file to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.
