  "details" : [ "The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the Linux kernel version 2.6.32 and up to and including 4.13.1, are vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space.", "A stack buffer overflow flaw was found in the way the Bluetooth subsystem of the Linux kernel processed pending L2CAP configuration responses from a client. On systems with the stack protection feature enabled in the kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other than s390x and ppc64[le]), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to crash the system. Due to the nature of the stack protection feature, code execution cannot be fully ruled out, although we believe it is unlikely. On systems without the stack protection feature (ppc64[le]; the Bluetooth modules are not built on s390x), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to remotely execute arbitrary code on the system with ring 0 (kernel) privileges." ],
  "statement" : "This issue does not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 5.\nThis issue affects the version of the kernel packages as shipped with Red Hat Enterprise Linux 6 and 7, and Red Hat Enterprise MRG 2. Future kernel updates for Red Hat Enterprise MRG 2 will address this issue.\nFor further information please refer to the vulnerability article in the Customer Portal: https://access.redhat.com/security/vulnerabilities/blueborne",
