______________________________________________________________________________

Announcement ID:    SUSE-SU-2017:2475-1
Rating:             important
References:         #1042892 #1046191 #1052311 #1052368 
Cross-References:   CVE-2017-1000112 CVE-2017-7645 CVE-2017-9242
                   
Affected Products:
                    SUSE Linux Enterprise Server 12-LTSS
______________________________________________________________________________

   An update that solves three vulnerabilities and has one
   errata is now available.

Description:

   This update for the Linux Kernel 3.12.61-52_86 fixes several issues.

   The following security bugs were fixed:

   - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
     in the Linux kernel was too late in checking whether an overwrite of an
     skb data structure may occur, which allowed local users to cause a
     denial of service (system crash) via crafted system calls (bsc#1042892).
   - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux
     kernel allowed remote attackers to cause a denial of service (system
     crash) via a long RPC reply (bsc#1046191).

   Alternatively you can run the command listed for your product:
