______________________________________________________________________________

 

An update that fixes three vulnerabilities is now available.

 

Description:

 

This update for the Linux Kernel 3.12.51-60_25 fixes several issues.

 

The following security bugs were fixed:

- CVE-2016-6480: Race condition in the ioctl_send_fib function in

drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed 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

(bsc#991667).

- CVE-2016-5829: Multiple heap-based buffer overflows in the

hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux

kernel allowed local users to cause a denial of service or possibly have

unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2)

HIDIOCSUSAGES ioctl call (bsc#986573).

- CVE-2016-4997: The compat IPT_SO_SET_REPLACE setsockopt implementation

in the netfilter subsystem in the Linux kernel allowed local users to

gain privileges or cause a denial of service (memory corruption) by

leveraging in-container root access to provide a crafted offset value

that triggers an unintended decrement (bsc#986377).
