  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-3791.NASL
    description Several 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

    NASL id UBUNTU_USN-3208-2.NASL
    description USN-3208-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that the generic SCSI block layer in the Linux kernel did not properly restrict write operations in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-10088) CAI Qian discovered that the sysctl implementation in the Linux kernel did not properly perform reference counting in some situations. An unprivileged attacker could use this to cause a denial of service (system hang). (CVE-2016-9191) Jim Mattson discovered that the KVM implementation in the Linux kernel mismanages the #BP and #OF exceptions. A local attacker in a guest virtual machine could use this to cause a denial of service (guest OS crash). (CVE-2016-9588) Andy Lutomirski and Willy Tarreau discovered that the KVM implementation in the Linux kernel did not properly emulate instructions on the SS segment register. A local attacker in a guest virtual machine could use this to cause a denial of service (guest OS crash) or possibly gain administrative privileges in the guest OS. (CVE-2017-2583) Dmitry Vyukov discovered that the KVM implementation in the Linux kernel improperly emulated certain instructions. A local attacker could use this to obtain sensitive information (kernel memory). (CVE-2017-2584) It was discovered that the KLSI KL5KUSB105 serial-to-USB device driver in the Linux kernel did not properly initialize memory related to logging. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-5549) Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2017-6074). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
