Security Fix(es) :

* A race condition flaw was found in the N_HLDC Linux kernel driver
when accessing n_hdlc.tbuf list that can lead to double free. A local,
unprivileged user able to set the HDLC line discipline on the tty
device could use this flaw to increase their privileges on the system.

* A flaw was found in the Linux kernel key management subsystem in
which a local attacker could crash the kernel or corrupt the stack and
additional memory (denial of service) by supplying a specially crafted
RSA key. This flaw panics the machine during the verification of the
RSA key. (CVE-2016-8650, Moderate)

* A flaw was found in the Linux kernel's implementation of setsockopt
for the SO_{SND|RCV}BUFFORCE setsockopt() system call. Users with
non-namespace CAP_NET_ADMIN are able to trigger this call and create a
situation in which the sockets sendbuff data size could be negative.
This could adversely affect memory allocations and create situations
where the system could crash or cause memory corruption.
(CVE-2016-9793, Moderate)

* A flaw was found in the Linux kernel's handling of clearing SELinux
attributes on /proc/pid/attr files. An empty (null) write to this file
can crash the system by causing the system to attempt to access
unmapped kernel memory. (CVE-2017-2618, Moderate)

Red Hat would like to thank Alexander Popov for reporting
CVE-2017-2636 and Ralf Spenneberg for reporting CVE-2016-8650. The
CVE-2017-2618 issue was discovered by Paul Moore (Red Hat
Engineering).

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

  - A flaw was found in the Linux kernel key management
    subsystem in which a local attacker could crash the
    kernel or corrupt the stack and additional memory
    (denial of service) by supplying a specially crafted
    RSA key. This flaw panics the machine during the
    verification of the RSA key. (CVE-2016-8650)

  - A flaw was found in the Linux kernel's implementation
    of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt()
    system call. Users with non-namespace CAP_NET_ADMIN are
    able to trigger this call and create a situation in
    which the sockets sendbuff data size could be negative.
    This could adversely affect memory allocations and
    create situations where the system could crash or cause
    memory corruption. (CVE-2016-9793)

  - A flaw was found in the Linux kernel's handling of
    clearing SELinux attributes on /proc/pid/attr files. An
    empty (null) write to this file can crash the system by
    causing the system to attempt to access unmapped kernel
    memory. (CVE-2017-2618)

  - The keyring_search_aux function in
    security/keys/keyring.c in the Linux kernel through
    3.14.79 allows local users to cause a denial of service
    (NULL pointer dereference and OOPS) via a request_key
    system call for the 'dead' type.(CVE-2017-6951)

    descriptionAn update for kernel-rt is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es) : * A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system. (CVE-2017-2636, Important) * A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650, Moderate) * A flaw was found in the Linux kernel

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts. - CVE-2016-6786 / CVE-2016-6787 It was discovered that the performance events subsystem does not properly manage locks during certain migrations, allowing a local attacker to escalate privileges. This can be mitigated by disabling unprivileged use of performance events:sysctl kernel.perf_event_paranoid=3 - CVE-2016-8405 Peter Pi of Trend Micro discovered that the frame buffer video subsystem does not properly check bounds while copying color maps to userspace, causing a heap buffer out-of-bounds read, leading to information disclosure. - CVE-2016-9191 CAI Qian discovered that reference counting is not properly handled within proc_sys_readdir in the sysctl implementation, allowing a local denial of service (system hang) or possibly privilege escalation. - CVE-2017-2583 Xiaohan Zhang reported that KVM for amd64 does not correctly emulate loading of a null stack selector. This can be used by a user in a guest VM for denial of service (on an Intel CPU) or to escalate privileges within the VM (on an AMD CPU). - CVE-2017-2584 Dmitry Vyukov reported that KVM for x86 does not correctly emulate memory access by the SGDT and SIDT instructions, which can result in a use-after-free and information leak. - CVE-2017-2596 Dmitry Vyukov reported that KVM leaks page references when emulating a VMON for a nested hypervisor. This can be used by a privileged user in a guest VM for denial of service or possibly to gain privileges in the host. - CVE-2017-2618 It was discovered that an off-by-one in the handling of SELinux attributes in /proc/pid/attr could result in local denial of service. - CVE-2017-5549 It was discovered that the KLSI KL5KUSB105 serial USB device driver could log the contents of uninitialised kernel memory, resulting in an information leak. - CVE-2017-5551 Jan Kara found that changing the POSIX ACL of a file on tmpfs never cleared its set-group-ID flag, which should be done if the user changing it is not a member of the group-owner. In some cases, this would allow the user-owner of an executable to gain the privileges of the group-owner. - CVE-2017-5897 Andrey Konovalov discovered an out-of-bounds read flaw in the ip6gre_err function in the IPv6 networking code. - CVE-2017-5970 Andrey Konovalov discovered a denial-of-service flaw in the IPv4 networking code. This can be triggered by a local or remote attacker if a local UDP or raw socket has the IP_RETOPTS option enabled. - CVE-2017-6001 Di Shen discovered a race condition between concurrent calls to the performance events subsystem, allowing a local attacker to escalate privileges. This flaw exists because of an incomplete fix of CVE-2016-6786. This can be mitigated by disabling unprivileged use of performance events: sysctl kernel.perf_event_paranoid=3 - CVE-2017-6074 Andrey Konovalov discovered a use-after-free vulnerability in the DCCP networking code, which could result in denial of service or local privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it:echo >> /etc/modprobe.d/disable-dccp.conf install dccp false
