Description

This update for the Linux Kernel 3.12.67-60_64_21 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-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline (bsc#1027575).
  • 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).
  • CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bsc#1038564).
