Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Integer overflow (CVE-ID: CVE-2021-42019)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow. A remote administrator can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Improper Check for Unusual or Exceptional Conditions (CVE-ID: CVE-2021-42020)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
