Synopsis
The remote openSUSE host is missing a security update.
Description
The openSUSE Leap 42.2 kernel was updated to 4.4.87 to receive various security and bugfixes.
The following security bugs were fixed :
- CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ) was vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space (bnc#1057389).
- CVE-2017-14106: The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel allowed local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path (bnc#1056982).
- CVE-2017-11472: The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the operand cache and causes a kernel stack dump, which allowed 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 (bnc#1049580).
- 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-2017-12134: The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation (bnc#1051790 1053919).
