The SUSE Linux Enterprise 12 SP4 for Azure kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-15291: There was a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).

CVE-2019-14821: An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).

CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).

CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation.
This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).

CVE-2019-14835: A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could have used this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).

CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).

CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).

CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).

CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).

CVE-2019-15212

The syzkaller tool found that the rio500 driver does not work correctly if more than one device is bound to it. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15215

The syzkaller tool found a bug in the cpia2_usb driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15218

The syzkaller tool found that the smsusb driver did not validate that USB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15219

The syzkaller tool found that a device initialisation error in the sisusbvga driver could lead to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15220

The syzkaller tool found a race condition in the p54usb driver which could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15221

The syzkaller tool found that the line6 driver did not validate USB devices' maximum packet sizes, which could lead to a heap buffer overrun. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15292

The Hulk Robot tool found missing error checks in the Appletalk protocol implementation, which could lead to a use-after-free. The security impact of this is unclear.

CVE-2019-15807

Jian Luo reported that the Serial Attached SCSI library (libsas) did not correctly handle failure to discover devices beyond a SAS expander. This could lead to a resource leak and crash (BUG). The security impact of this is unclear.

CVE-2019-15917

The syzkaller tool found a race condition in code supporting UART-attached Bluetooth adapters, which could lead to a use- after-free. A local user with access to a pty device or other suitable tty device could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15926

It was found that the ath6kl wifi driver did not consistently validate traffic class numbers in received control packets, leading to out-of-bounds memory accesses. A nearby attacker on the same wifi network could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version 3.16.74-1.

We recommend that you upgrade your linux packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

The Linux Kernel KVM hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-11135:
Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233:
drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150457).

CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150452).

CVE-2019-17055: The AF_ISDN network module in the Linux kernel did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bnc#1152782).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bsc#1152788).

CVE-2019-16413: The 9p filesystem did not protect i_size_write() properly, which caused an i_size_read() infinite loop and denial of service on SMP systems (bnc#1151347).

CVE-2019-15902: A backporting issue was discovered that re-introduced the Spectre vulnerability it had aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).

CVE-2019-15291: Fixed a NULL pointer dereference issue that could be caused by a malicious USB device (bnc#11465).

CVE-2019-15807: Fixed a memory leak in the SCSI module that could be abused to cause denial of service (bnc#1148938).

CVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip driver was fixed. Local users would have abused this issue to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146516).

CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific socket option, an attacker could control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and inject arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath was fixed (bnc#1146378).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14218-1 advisory.

  - An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket     option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general     protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be     triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after     namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of     the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before     4.9.187. (CVE-2017-18509)

  - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an     out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)

  - Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to potentially enable denial of service of the host system via     local access. (CVE-2018-12207)

  - An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated     user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135)

  - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux     kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer     'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be     supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm'     device could use this flaw to crash the host kernel, resulting in a denial of service or potentially     escalating privileges on the system. (CVE-2019-14821)

  - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost     functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A     privileged guest user able to pass descriptors with invalid length to the host when migration is underway,     could use this flaw to increase their privileges on the host. (CVE-2019-14835)

  - check_input_term in sound/usb/mixer.c in the Linux kernel through 5.2.9 mishandles recursion, leading to     kernel stack exhaustion. (CVE-2019-15118)

  - An issue was discovered in the Linux kernel before 5.1.8. There is a double-free caused by a malicious USB     device in the drivers/usb/misc/rio500.c driver. (CVE-2019-15212)

  - An issue was discovered in the Linux kernel before 5.0.14. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/usb/misc/yurex.c driver. (CVE-2019-15216)

  - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)

  - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver. (CVE-2019-15219)

  - An issue was discovered in the Linux kernel through 5.2.9. There is a NULL pointer dereference caused by a     malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver.
    (CVE-2019-15291)

  - An issue was discovered in the Linux kernel before 5.0.9. There is a use-after-free in atalk_proc_exit,     related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c.
    (CVE-2019-15292)

  - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via     crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)

  - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)

  - A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x     through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the     upstream x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg() commit reintroduced the Spectre     vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry     picking specific commits, and because two (correctly ordered) code lines were swapped. (CVE-2019-15902)

  - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function     build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)

  - drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16232)

  - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16233)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16234)

  - An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.
    (CVE-2019-16413)

  - ax25_create in net/ax25/af_ax25.c in the AF_AX25 network module in the Linux kernel 3.16 through 5.3.2     does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-0614e2b73768. (CVE-2019-17052)

  - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel     through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket,     aka CID-e69dbd4619e7. (CVE-2019-17053)

  - atalk_create in net/appletalk/ddp.c in the AF_APPLETALK network module in the Linux kernel through 5.3.2     does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-6cc03e8aa36c. (CVE-2019-17054)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - In the Android kernel in Pixel C USB monitor driver there is a possible OOB write due to a missing bounds     check. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation. (CVE-2019-9456)
