VUL-0: CVE-2013-4738: kernel-source: MSM camera driver multiple vulnerabilities
Last modified: 2016-04-27 19:11:10 UTC
CVE-2013-4738 and CVE-2013-4739 A stack-based buffer overflow and a kernel memory disclosure vulnerability have been discovered in the system call handlers of the camera driver. CVE-2013-4738: The camera post processing engine (CPP) and video processing engine (VPE) provide an ioctl system call interface to user space clients for communication. When processing arguments passed to the VIDIOC_MSM_CPP_DEQUEUE_STREAM_BUFF_INFO or VIDIOC_MSM_VPE_DEQUEUE_STREAM_BUFF_INFO ioctl subdev handlers, a user space supplied length value is used to copy memory to a local stack buffer without proper bounds checking. An application with access to the respective device nodes can use this flaw to, e.g., elevate privileges. Access Vector: local Security Risk: high Vulnerability: CWE-121 (stack-based buffer overflow) CVE-2013-4739: The Gemini JPEG encoder and the Jpeg1.0 common encoder/decoder engines of the camera driver are not properly initializing all members of a structure before copying it to user space. This allows a local attacker to obtain potentially sensitive information from kernel stack memory via ioctl system calls. Access Vector: local Security Risk: low Vulnerability: CWE-200 (information exposure) Affected versions All Android releases from CAF using a Linux kernel from the following heads: *PATCHES* CVE-2013-4738: https://www.codeaurora.org/cgit/quic/la/kernel/msm/commit/?id=c9c81836ee44db9974007d34cf2aaeb1a51a8d45 https://www.codeaurora.org/cgit/quic/la/kernel/msm/commit/?id=28385b9c3054c91dca1aa194ffa750550c50f3ce CVE-2013-4739: https://www.codeaurora.org/cgit/quic/la/kernel/msm/commit/?id=8604847927f952cc8e773b97eca24e1060a570f2 References: http://www.openwall.com/lists/oss-security/2013/10/15/4 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4738 http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-4738

This seems to be not from mainline, but in some kind of Android branch, not in mainline. It is invalid.
