Vitaly Mayatskikh discovered that the SCSI subsystem in the Linux kernel did not properly track reference counts when merging buffers. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2017-12190)

It was discovered that the key management subsystem in the Linux kernel did not properly restrict key reads on negatively instantiated keys. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-12192)

It was discovered that an integer overflow existed in the sysfs interface for the QLogic 24xx+ series SCSI driver in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-14051)

Otto Ebeling discovered that the memory manager in the Linux kernel did not properly check the effective UID in some situations. A local attacker could use this to expose sensitive information. (CVE-2017-14140)

It was discovered that the ATI Radeon framebuffer driver in the Linux kernel did not properly initialize a data structure returned to user space. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-14156)

ChunYu Wang discovered that the iSCSI transport implementation in the Linux kernel did not properly validate data structures. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14489)

James Patrick-Evans discovered a race condition in the LEGO USB Infrared Tower driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15102)

ChunYu Wang discovered that a use-after-free vulnerability existed in the SCTP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code, (CVE-2017-15115)

It was discovered that the key management subsystem in the Linux kernel did not properly handle NULL payloads with non-zero length values. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-15274)

It was discovered that the Bluebooth Network Encapsulation Protocol (BNEP) implementation in the Linux kernel did not validate the type of socket passed in the BNEPCONNADD ioctl(). A local attacker with the CAP_NET_ADMIN privilege could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15868)

Andrey Konovalov discovered a use-after-free vulnerability in the USB serial console driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16525)

It was discovered that the netfilter passive OS fingerprinting (xt_osf) module did not properly perform access control checks. A local attacker could improperly modify the systemwide OS fingerprint list. (CVE-2017-17450)

It was discovered that the HMAC implementation did not validate the state of the underlying cryptographic hash algorithm. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-17806)

Denys Fedoryshchenko discovered a use-after-free vulnerability in the netfilter xt_TCPMSS filter of the Linux kernel. A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-18017)

Gareth Evans discovered that the shm IPC subsystem in the Linux kernel did not properly restrict mapping page zero. A local privileged attacker could use this to execute arbitrary code. (CVE-2017-5669)

It was discovered that an integer overflow vulnerability existing in the IPv6 implementation in the Linux kernel. A local attacker could use this to cause a denial of service (infinite loop). (CVE-2017-7542)

Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889)

Mohamed Ghannam discovered a use-after-free vulnerability in the DCCP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-8824)

Mohamed Ghannam discovered a null pointer dereference in the RDS (Reliable Datagram Sockets) protocol implementation of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-5333)

范龙飞 discovered that a race condition existed in loop block device implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5344)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04 ESM:
linux-image-3.13.0-142-generic 3.13.0-142.191~precise1
linux-image-3.13.0-142-generic-lpae 3.13.0-142.191~precise1
linux-image-generic-lpae-lts-trusty 3.13.0.142.133
linux-image-generic-lts-trusty 3.13.0.142.133

After a standard system update you need to reboot your computer to make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
