Security Advisory - DoS Vulnerabilities in JPU Driver of Huawei Products

  • SA No:Huawei-SA-20151210-01-JPU
  • Initial Release Date: 2015-12-10
  • Last Release Date: 2015-12-10

There are two Denial of Service (DoS) vulnerabilities in Joint Photographic Experts Group Processing Unit (JPU) drivers of some Huawei products. An attacker who tricks a user into installing a malicious application which has the system or camera permission may input invalid parameters into the JPU driver program to crash the product system. (Vulnerability ID: HWPSIRT-2015-10040 and HWPSIRT-2015-10041)

These vulnerabilities have been assigned Common Vulnerabilities and Exposures (CVE) IDs: CVE-2015-8225 and CVE-2015-8226.

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

An attacker may exploit this vulnerability to crash the product system.

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

HWPSIRT-2015-10040:

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)

HWPSIRT-2015-10041:

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 device and obtains the system or camera permission.

2. Attacking procedure:

The JPU driver has two DoS vulnerabilities due to the insufficient validation of the specific external input parameters. An attacker who tricks a user into installing a malicious application which has the system or camera permission may input invalid parameters into the JPU driver program to crash the product system.
