According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found where the kernel truncated the value     used to indicate the size of a buffer which it would     later become zero using an untruncated value. This can     corrupt memory outside of the original     allocation.(CVE-2017-9725)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5753 triggers the     speculative execution by performing a bounds-check     bypass. It relies on the presence of a     precisely-defined instruction sequence in the     privileged code as well as the fact that memory     accesses may cause allocation into the microprocessor's     data cache even for speculatively executed instructions     that never actually commit (retire). As a result, an     unprivileged attacker could use this flaw to cross the     syscall boundary and read privileged memory by     conducting targeted cache side-channel     attacks.(CVE-2017-5753)

  - A buffer overflow was found in the Linux kernel's     isdn_net_newslave() function in the     /drivers/isdn/i4l/isdn_net.c file. An overflow happens     when the user-controlled buffer is copied into a local     buffer of constant size using strcpy() without a length     check.(CVE-2017-12762)

  - Modern operating systems implement virtualization of     physical memory to efficiently use available system     resources and provide inter-domain protection through     access control and isolation. The L1TF issue was found     in the way the x86 microprocessor designs have     implemented speculative execution of instructions (a     commonly used performance optimization) in combination     with handling of page-faults caused by terminated     virtual to physical address resolving process. As a     result, an unprivileged attacker could use this flaw to     read privileged memory of the kernel or other processes     and/or cross guest/host boundaries to read host memory     by conducting targeted cache side-channel     attacks.(CVE-2018-3646)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5715 triggers the     speculative execution by utilizing branch target     injection. It relies on the presence of a     precisely-defined instruction sequence in the     privileged code as well as the fact that memory     accesses may cause allocation into the microprocessor's     data cache even for speculatively executed instructions     that never actually commit (retire). As a result, an     unprivileged attacker could use this flaw to cross the     syscall and guest/host boundaries and read privileged     memory by conducting targeted cache side-channel     attacks.(CVE-2017-5715)

  - In hid_debug_events_read of drivers/hid/hid-debug.c,     there is a possible out of bounds 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. Product: Android Versions: Android kernel     Android ID: A-71361580.(CVE-2018-9516)

  - Systems with microprocessors utilizing speculative     execution and speculative execution of memory reads     before the addresses of all prior memory writes are     known may allow unauthorized disclosure of information     to an attacker with local user access via a     side-channel analysis, aka Speculative Store Bypass     (SSB), Variant 4.(CVE-2018-3639)

  - It was found that the Linux kernel memory resource     controller's (memcg) handling of OOM (out of memory)     conditions could lead to deadlocks. An attacker able to     continuously spawn new processes within a single     memory-constrained cgroup during an OOM event could use     this flaw to lock up the system.(CVE-2014-8171)

  - In sk_clone_lock of sock.c, there is a possible memory     corruption due to type confusion. This could lead to     local escalation of privilege with no additional     execution privileges needed. User interaction is not     needed for exploitation. Product: Android. Versions:
    Android kernel. Android ID: A-113509306. References:

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important)

* A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2015-1421, Important)

* It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system.
(CVE-2014-3690, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system.
(CVE-2014-7825, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges.
(CVE-2014-7826, Moderate)

* It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate)

* A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate)

* A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system.
(CVE-2014-8884, Low)

* An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low)

Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-3215 and CVE-2014-3690, Robert Swiecki for reporting CVE-2014-7825 and CVE-2014-7826, and Carl Henrik Lunde for reporting CVE-2014-9584. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat.

This update also fixes several bugs. Documentation for these changes is available from the Technical Notes document linked to in the References section.

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
