An update that fixes three vulnerabilities is now available.

 

Description:

 

This update for the Linux Kernel 3.12.61-52_80 fixes several issues.

 

The following security bugs were fixed:

 

- CVE-2017-7533: A bug in inotify code allowed local users to escalate

privilege (bsc#1050751).

- 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, related to net/sunrpc/svc.c,

fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c (bsc#1046191).

- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c

in the Linux kernel is 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).
