Synopsis

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

Description

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

- 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-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-2017-16529: 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).

- CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667).

- CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327).

- CVE-2017-15265: Race condition in the ALSA subsystem in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted /dev/snd/seq ioctl calls, related to sound/core/seq/seq_clientmgr.c and sound/core/seq/seq_ports.c (bnc#1062520).

- CVE-2017-14489: The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel allowed local users to cause a denial of service (panic) by leveraging incorrect length validation (bnc#1059051).

- CVE-2017-14340: The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel did not verify that a filesystem has a realtime device, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory (bnc#1058524).

- CVE-2017-14140: The move_pages system call in mm/migrate.c in the Linux kernel doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179).

- CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588).

- CVE-2017-10661: Race condition in fs/timerfd.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bnc#1053152).

- CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. (bnc#1053148).

- CVE-2017-8831: The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a 'double fetch' vulnerability (bnc#1037994).

- CVE-2017-1000112: An exploitable memory corruption due to UFO to non-UFO path switch was fixed. (bnc#1052311 bnc#1052365).

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