Affected Projects:
Android for MSMFirefox OS for MSMQRD Android
Advisory ID:
QCIR-2014-00001-1
CVE ID(s):
Summary:
The following security vulnerabilities have been identified in the camera driver. CVE-2013-6123: The camera driver provides an ioctl system call interface to user space clients for communication. When processing this communication, the msm_ioctl_server, msm_server_send_ctrl, and msm_ctrl_cmd_done functions use a user-supplied value as an index to the server_queue array for read and write operations without any boundary checks. A local application with access to the camera device nodes can use this flaw to, e.g., elevate privileges.
