Advisory ID QCIR-2013-00005-1 CVE ID(s) CVE-2013-4736 Description The following security vulnerability has been identified in the MSM JPEG engine drivers (Gemini JPEG encoder, Mercury JPEG decoder, Jpeg1.0 common encoder/decoder). CVE-2013-4736: The JPEG engines that are part of the camera driver provide an ioctl system call interface to user space clients for communication. When processing hardware commands ioctl calls, the drivers are incorrectly handling the number of commands included in the user space payload. This can lead to an integer overflow which subsequently results in the driver attempting to process hardware commands from out-of-bounds memory which can cause the kernel to crash. The same code also suffered from incorrectly treating the number of hardware commands as signed. Access Vector: local Security Risk: medium Vulnerability: integer overflow (CWE-190) Affected versions All Android releases from CAF using a Linux kernel from the following heads: msm-3.* jb* ics* gingerbread* Patch We advise customers to apply the following patches for individual branches.
