  • Last Release Date: 2016-02-03

There are multiple security vulnerabilities in driver of some Huawei smart phones.

There are two interface access control vulnerabilities in Graphics driver. An attacker may trick a user into installing a malicious application and application can exploit the vulnerability to crash the system or escalate user privilege. (Vulnerability ID: HWPSIRT-2015-11010 and HWPSIRT-2015-11091)

The vulnerability HWPSIRT-2015-11010 has been assigned Common Vulnerabilities and Exposures (CVE) ID: CVE-2015-8307, the vulnerability HWPSIRT-2015-11091 has been assigned CVE ID: CVE-2015-8680.

There are two heap overflow vulnerabilities in HIFI driver. An attacker may trick a user into installing a malicious application and the application can send given parameter to HIFI driver to crash the system or escalate user privilege. (Vulnerability ID: HWPSIRT-2015-11028 and HWPSIRT-2015-11029)

The vulnerability HWPSIRT-2015-11028 has been assigned CVE ID: CVE-2015-8318, the vulnerability HWPSIRT-2015-11029 has been assigned CVE ID: CVE-2015-8319.

There is a interface access control vulnerability in ovisp driver. An attacker may trick a user into installing a malicious application and application can exploit the vulnerability to crash the system or escalate user privilege. (Vulnerability ID: HWPSIRT-2015-12003)

This vulnerability has been assigned CVE ID: CVE-2015-8681.

Huawei has released software updates to fix those vulnerabilities. This advisory is available at the following link:

[1] Mobile phones will receive a system update prompt. The vulnerability will be fixed after users install the update.

HWPSIRT-2015-11010 & HWPSIRT-2015-11028 & HWPSIRT-2015-11029 & HWPSIRT-2015-11091 & HWPSIRT-2015-12003:

The malicious application installed in smart phone can exploit this vulnerability to crash the system or escalate user privilege.

The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).

HWPSIRT-2015-11010 & HWPSIRT-2015-11028 & HWPSIRT-2015-11029 & HWPSIRT-2015-11091 & HWPSIRT-2015-12003:

Base Score: 6.2 (AV:L/AC:H/Au:N/C:C/I:C/A:C)

Temporal Score: 5.1 (E:F/RL:O/RC:C)

HWPSIRT-2015-11010 & HWPSIRT-2015-11091:

1. Prerequisite:

The attacker successfully tricks a user into installing a malicious application on the smart phone.

2. Attacking procedure:

There are two interface access control vulnerabilities in Graphics driver. An attacker may trick a user into installing a malicious application; the application can get graphics privilege and exploit these vulnerabilities to modify the content of some registers, which could cause the system to crash or user privilege to escalate.

HWPSIRT-2015-11028 & HWPSIRT-2015-11029:

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. Therefore, the application may exploit this vulnerability to make a heap overflow and read and modify phone memory address, which can crash the system or escalate user privilege.

HWPSIRT-2015-12003:

1. Prerequisite:

The attacker successfully tricks a user into installing a malicious application on the smart phone.

2. Attacking procedure:

There is a interface access control vulnerability in ovisp driver. An attacker may trick a user into installing a malicious application. The application can get camera privilege and exploit this vulnerability to modify content of some registers, which could cause the system to crash or user privilege to escalate.

1. Mobile phones that support automatic update will receive a system update prompt. You can install the update to fix the vulnerabilities.
2. 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/psirt/report-vulnerabilities.
