High Nessus Plugin ID 105020

Synopsis

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

Description

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

- CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages. (bnc#1069702)

- CVE-2017-1000405: mm, thp: do not dirty huge pages on read fault (bnc#1069496).

- CVE-2017-16649: The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel allowed local users to cause a denial of service (divide-by-zero error and system crash) or possibly have unspecified other impact via a crafted USB device. (bnc#1067085)

- CVE-2014-0038: The compat_sys_recvmmsg function in net/compat.c, when CONFIG_X86_X32 is enabled, allowed local users to gain privileges via a recvmmsg system call with a crafted timeout pointer parameter (bnc#860993).

- CVE-2017-16650: The qmi_wwan_bind function in drivers/net/usb/qmi_wwan.c in the Linux kernel allowed local users to cause a denial of service (divide-by-zero error and system crash) or possibly have unspecified other impact via a crafted USB device. (bnc#1067086)

- CVE-2017-16535: The usb_get_bos_descriptor function in drivers/usb/core/config.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device. (bnc#1066700)

- CVE-2017-15102: The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel allowed local users (who are physically proximate for inserting a crafted USB device) to gain privileges by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference.
(bnc#1066705)

- CVE-2017-16531: drivers/usb/core/config.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device, related to the USB_DT_INTERFACE_ASSOCIATION descriptor.
(bnc#1066671)

- 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-2017-16529: The snd_usb_create_streams function in sound/usb/card.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device. (bnc#1066650)

- CVE-2017-16525: The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel allowed local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup. (bnc#1066618)

- 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-2017-16536: 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-2017-16527: sound/usb/mixer.c in the Linux kernel allowed local users to cause a denial of service (snd_usb_mixer_interrupt use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device. (bnc#1066625)

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