[1] Mobile phones will receive a system update prompt. The vulnerabilities will be fixed after users install the update.
An attacker may exploit these two vulnerabilities to reboot the system.
These two vulnerabilities classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).
Base Score: 4.0 (AV:L/AC:H/Au:N/C:N/I:N/A:C)
Temporal Score: 3.3 (E:F/RL:O/RC:C)1. Prerequisite:
The attacker successfully tricks a user into installing a malicious application on the smart phone.
2. Attacking procedure:
The attacker tricks a user into installing a malicious application on the phone. The malicious application can access specific HIFI driver interfaces of the phone by system calls. The HIFI driver does not properly validate the parameters input by the application and access the invalid address, which can make the system reboot.
- Mobile phones that support automatic update will receive a system update prompt. You can install the update to fix the vulnerabilities.
- Customers should obtain upgrades through Huawei consumer business official website (http://emui.huawei.com/cn/portal.php).
- Customers should contact Huawei TAC (Huawei Technical Assistance Center) to request the upgrades. For TAC contact information, please refer to Huawei worldwide website at http://www.huawei.com/en/security/psirt/report-vulnerabilities/index.htm.
