The openSUSE Leap 15.1 was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2019-11477: A sequence of SACKs may have been     crafted by a remote attacker such that one can trigger     an integer overflow, leading to a kernel panic.
    (bsc#1137586).

  - CVE-2019-11478: It was possible to send a crafted     sequence of SACKs which would fragment the TCP     retransmission queue. A remote attacker may have been     able to further exploit the fragmented queue to cause an     expensive linked-list walk for subsequent SACKs received     for that same TCP connection. (bsc#1137586)

  - CVE-2019-11479: It was possible to send a crafted     sequence of SACKs which would fragment the RACK send     map. A remote attacker may be able to further exploit     the fragmented send map to cause an expensive     linked-list walk for subsequent SACKs received for that     same TCP connection. This would have resulted in excess     resource consumption due to low mss values.
    (bsc#1137586)

  - CVE-2019-12819: The function __mdiobus_register() in     drivers/net/phy/mdio_bus.c calls put_device(), which     will trigger a fixed_mdio_bus_init use-after-free. This     will cause a denial of service (bnc#1138291).

  - CVE-2019-12818: The nfc_llcp_build_tlv function in     net/nfc/llcp_commands.c may return NULL. If the caller     did not check for this, it will trigger a NULL pointer     dereference. This will cause denial of service. This     affects nfc_llcp_build_gb in net/nfc/llcp_core.c     (bnc#1138293).

  - CVE-2019-12456: An issue was discovered in the     MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c that allowed local     users to cause a denial of service or possibly have     unspecified other impact by changing the value of     ioc_number between two kernel reads of that value, aka a     'double fetch' vulnerability. (bnc#1136922)

  - CVE-2019-12380: An issue was discovered in the efi     subsystem in the Linux kernel     phys_efi_set_virtual_address_map in     arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory     allocation failures (bnc#1136598).

  - CVE-2019-3846: A flaw that allowed an attacker to     corrupt memory and possibly escalate privileges was     found in the mwifiex kernel module while connecting to a     malicious wireless network (bnc#1136424).

  - CVE-2019-10124: An attacker could exploit an issue in     the hwpoison implementation to cause a denial of service     (BUG). (bsc#1130699)

  - CVE-2019-12382: In the drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c was an unchecked kstrdup     of fwstr, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash) (bnc#1136586).

  - CVE-2019-11487: The Linux kernel allowed page->_refcount     reference count overflow, with resultant use-after-free     issues, if about 140 GiB of RAM exists. This is related     to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c.

    An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in     drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.

The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols.
When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575]

CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass.
Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server.
ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. [bnc#1140577]

CVE-2018-20836: A race condition used to exist in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. [bnc#1134395]

CVE-2019-10126: A heap-based buffer overflow in the wireless driver code was fixed. This issue might have lead to memory corruption and possibly other consequences. [bnc#1136935]

CVE-2019-11599: The coredump implementation did not use locking or other mechanisms to prevent vma layout or vma flags changes while it ran, which allowed local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.
[bnc#1131645].

CVE-2019-12614: There was an unchecked kstrdup of prop->name on PowerPC platforms, which allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). [bnc#1137194]

CVE-2018-16871: A flaw was found in the NFS implementation. An attacker who was able to mount an exported NFS filesystem was able to trigger a NULL pointer dereference by an invalid NFS sequence. This could panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will were lost.
[bnc#1137103]

CVE-2019-12819: The function __mdiobus_register() used to call put_device(), which would trigger a fixed_mdio_bus_init use-after-free error. This would cause a denial of service. [bnc#1138291]

CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller did not check for this, it could trigger a NULL pointer dereference. This would cause denial of service. [bnc#1138293]

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main() allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability.
[bsc#1136922]

CVE-2019-12380: An issue was in the EFI subsystem existed that mishandled memory allocation failures. Note, however, that all relevant code runs only at boot-time, before any user processes are started. Therefore, there was no possibility for an unprivileged user to exploit this issue. [bnc#1136598]
