High Nessus Plugin ID 105460

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.103 to receive various security and bugfixes. The following security bugs were fixed :

- CVE-2017-1000410: The Linux kernel was affected by an information lea that lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. (bnc#1070535).

- CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux kernel did not ensure that the dir value of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message (bnc#1050231).

- CVE-2017-12193: The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel mishandled node splitting, which allowed local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations (bnc#1066192).

- CVE-2017-15115: The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel did not check whether the intended netns is used in a peel-off action, which allowed local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls (bnc#1068671).

- CVE-2017-16528: sound/core/seq_device.c in the Linux kernel allowed local users to cause a denial of service (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066629).

- CVE-2017-16536: The cx231xx_usb_probe function in drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066606).

- CVE-2017-16537: The imon_probe function in drivers/media/rc/imon.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066573).

- CVE-2017-16645: The ims_pcu_get_cdc_union_desc function in drivers/input/misc/ims-pcu.c in the Linux kernel allowed local users to cause a denial of service (ims_pcu_parse_cdc_data out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067132).

- CVE-2017-16646:
drivers/media/usb/dvb-usb/dib0700_devices.c in the Linux kernel allowed local users to cause a denial of service (BUG and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067105).

- CVE-2017-16994: The walk_hugetlb_range function in mm/pagewalk.c in the Linux kernel mishandled holes in hugetlb ranges, which allowed local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call (bnc#1069996).

- CVE-2017-17448: net/netfilter/nfnetlink_cthelper.c in the Linux kernel did not require the CAP_NET_ADMIN capability for new, get, and del operations, which allowed local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces (bnc#1071693).

- CVE-2017-17449: The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel did not restrict observations of Netlink messages to a single net namespace, which allowed local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system (bnc#1071694).

- CVE-2017-17450: net/netfilter/xt_osf.c in the Linux kernel did not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allowed local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces (bnc#1071695).

- CVE-2017-7482: Fixed an overflow when decoding a krb5 principal. (bnc#1046107).

- CVE-2017-8824: The dccp_disconnect function in net/dccp/proto.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state (bnc#1070771).

The update package also includes non-security fixes. See advisory for details.
