flash-plugin: information disclosure issues fixed in APSB17-21

Adobe Flash Player versions 26.0.0.131 and earlier have a security bypass vulnerability related to the Flash API used by Internet Explorer. Successful exploitation could lead to information disclosure.

kernel: ACPI operand cache leak in dsutils.c

The acpi_ds_create_operands() function in drivers/acpi/acpica/dsutils.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.

kernel: ACPI node and node_ext cache leak

The acpi_ps_complete_final_op() function in drivers/acpi/acpica/psobject.c in the Linux kernel through 4.12.9 does not flush the node and node_ext caches and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.

kernel: ACPI operand cache leak in nseval.c

The acpi_ns_evaluate() function in drivers/acpi/acpica/nseval.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.

kernel: Integer overflow in the qla2x00_sysfs_write_optrom_ctl function

An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access.

kernel: driver/video/fbdev/aty/atyfb_base.c: atyfb_ioctl() stack infoleak

The atyfb_ioctl function in drivers/video/fbdev/aty/atyfb_base.c in the Linux kernel through 4.12.10 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading locations associated with padding bytes.

kernel: xfs: unprivileged user kernel oops

The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel before 4.13.2 does not verify that a filesystem has a realtime device, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory.

kernel: scsi: nlmsg is not properly parsed in iscsi_if_rx function

The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel through 4.13.2 allows local users to cause a denial of service (panic) by leveraging incorrect length validation.

IBM DB2 for Linux, UNIX and Windows 9.7, 10,1, 10.5, and 11.1 (includes DB2 Connect Server) could allow a local user with DB2 instance owner privileges to obtain root access. IBM X-Force ID: 128178.

kernel: Information leak in the scsi driver

The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel before 4.13.4 allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for /dev/sg0.

kernel: NULL pointer dereference due to race condition in probe function of legousbtower driver

The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel before 4.8.1 allows 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.

IBM DB2 10.5 and 11.1 contains a denial of service vulnerability. A remote user can cause disruption of service for DB2 Connect Server setup with a particular configuration. IBM X-Force ID: 129829.

kernel: bnep_add_connection does not check if l2cap socket is available allowing privilege escalation

The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.

kernel: Use-after-free in snd_usb_mixer_interrupt

sound/usb/mixer.c in the Linux kernel before 4.13.8 allows 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.

kernel: use-after-free in snd_rawmidi_dev_seq_free

sound/core/seq_device.c in the Linux kernel before 4.13.4 allows 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.

kernel: out-of-bounds read in snd_usb_create_streams

The snd_usb_create_streams function in sound/usb/card.c in the Linux kernel before 4.13.6 allows 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.

kernel: out-of-bounds read in drivers/usb/storage/uas-detect{.h,.c}

The uas driver in the Linux kernel before 4.13.6 allows 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 drivers/usb/storage/uas-detect.h and drivers/usb/storage/uas.c.

kernel: out-of-bounds read in drivers/usb/core/config.c

drivers/usb/core/config.c in the Linux kernel before 4.13.6 allows 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.

kernel: Divide-by-zero in drivers/net/usb/qmi_wwan.c

The qmi_wwan_bind function in drivers/net/usb/qmi_wwan.c in the Linux kernel through 4.13.11 allows 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.

kernel: Divide-by-zero in drivers/net/usb/cdc_ether.c

The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel through 4.13.11 allows 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.
