net/ipv4/tcp_input.c in the Linux kernel before 4.7 does not properly determine the rate of challenge ACK segments, which makes it easier for man-in-the-middle attackers to hijack TCP sessions via a blind in-window attack.

CVE-2016-6136
Race condition in the audit_log_single_execve_arg function in kernel/auditsc.c in the Linux kernel through 4.7 allows local users to bypass intended character-set restrictions or disrupt system-call auditing by changing a certain string, aka a “double fetch” vulnerability.
CVE-2016-6156
Race condition in the ec_device_ioctl_xcmd function in drivers/platform/chrome/cros_ec_dev.c in the Linux kernel before 4.7 allows local users to cause a denial of service (out-of-bounds array access) by changing a certain size value, aka a “double fetch” vulnerability.
CVE-2016-6162
net/core/skbuff.c in the Linux kernel 4.7-rc6 allows local users to cause a denial of service (panic) or possibly have unspecified other impact via certain IPv6 socket operations.
CVE-2016-6187
The apparmor_setprocattr function in security/apparmor/lsm.c in the Linux kernel before 4.6.5 does not validate the buffer size, which allows local users to gain privileges by triggering an AppArmor setprocattr hook.
CVE-2016-6197
fs/overlayfs/dir.c in the OverlayFS filesystem implementation in the Linux kernel before 4.6 does not properly verify the upper dentry before proceeding with unlink and rename system-call processing, which allows local users to cause a denial of service (system crash) via a rename system call that specifies a self-hardlink.
CVE-2016-6198
The filesystem layer in the Linux kernel before 4.5.5 proceeds with post-rename operations after an OverlayFS file is renamed to a self-hardlink, which allows local users to cause a denial of service (system crash) via a rename system call, related to fs/namei.c and fs/open.c.
CVE-2016-6480
Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a “double fetch” vulnerability.
CVE-2016-6516
Race condition in the ioctl_file_dedupe_range function in fs/ioctl.c in the Linux kernel through 4.7 allows local users to cause a denial of service (heap-based buffer overflow) or possibly gain privileges by changing a certain count value, aka a “double fetch” vulnerability.
NUUO 3.0.8 strong_user.php Backdoor Remote Shell Access
NUUO NVRmini, NVRmini2, Crystal and NVRSolo devices have a hidden PHP script that when called, a backdoor user is created with poweruser privileges that is able to read and write files on the affected device. The backdoor user ‘bbb’ when created with the password ‘111111’ by visiting ‘strong_user.php’ script is able to initiate a secure shell session and further steal and/or destroy sensitive information.
