The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause the new connections can't be established, result in a denial of service condition.


2) Double Free (CVE-ID: CVE-2020-1829)

The vulnerability allows a remote attacker to compromise normal service.

The vulnerability exists due to a boundary error when the IPSec module handles a message improperly. A remote attacker can send specific message to affected product, trigger double free error and compromise normal service.


3) Input validation error (CVE-ID: CVE-2020-1827)

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

The vulnerability exists due to the IPSec Module handles a specific message incorrectly. A remote attacker can send a specially crafted message and cause a denial of service condition in IPSec module.

6) Access of Uninitialized Pointer (CVE-ID: CVE-2020-1875)

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

The vulnerability exists due to the affected software system access an invalid pointer when an abnormal condition occurs in certain operation. A local attacker can cause certain process reboot.


7) Access of Uninitialized Pointer (CVE-ID: CVE-2020-1874)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to the affected software system access an invalid pointer when operator logs in to the device and performs some operations. A local user can cause certain process reboot.


8) Memory leak (CVE-ID: CVE-2020-1883)

The vulnerability allows a remote user to perform denial fo service (DoS) attack on the target system.

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