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:

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.
