This update for the Linux Kernel 4.4.21-69 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-2017-8797: The NFSv4 server in the Linux kernel did not properly
    validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or
    LAYOUTGET operand in a UDP packet from a remote attacker. This type
    value is uninitialized upon encountering certain error conditions. This
    value is used as an array index for dereferencing, which leads to an
    OOPS and eventually a DoS of knfsd and a soft-lockup of the whole system
    (bsc#1046202)
  • 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-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c
    in the Linux kernel mishandled inheritance, which allowed local users to
    cause a denial of service or possibly have unspecified other impact via
    crafted system calls, a related issue to CVE-2017-8890 (bsc#1042364).
  • 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).
