References:         #960563 #964732 #966683 #967773 
Cross-References:   CVE-2015-8709 CVE-2015-8812 CVE-2016-0774

   An update that fixes four vulnerabilities is now available.


   This update for the Linux Kernel 3.12.43-52.6.1 fixes the following issues:

   - CVE-2016-2384: A malicious USB device could cause a kernel crash in the
     alsa usb-audio driver. (bsc#967773)

   - CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the
     network was considered congested.  The kernel would incorrectly
     misinterpret the congestion as an error condition and incorrectly
     free/clean up the skb. When the device would then send the skb's queued,
     these structures would be referenced and may panic the system or allow
     an attacker to escalate privileges in a use-after-free scenario.

   - CVE-2016-0774: A pipe buffer state corruption after unsuccessful atomic
     read from pipe was fixed (bsc#964732).

   - CVE-2015-8709: kernel/ptrace.c in the Linux kernel mishandled uid and
     gid mappings, which allowed local users to gain privileges by
     establishing a user namespace, waiting for a root process to enter that
     namespace with an unsafe uid or gid, and then using the ptrace system
     call. NOTE: the vendor states "there is no kernel bug here." (bsc#960563)
