  1. USN-2948-2

    Nicht bewertetKorrektur verfügbar

    linux-lts-utopic regression

    USN-2948-1 fixed vulnerabilities in the Ubuntu 14.10 Linux kernel backported to Ubuntu 14.04 LTS. An incorrect reference counting fix in the radeon driver introduced a regression that could cause a system crash. This update fixes the problem. We apologize for the inconvenience. Original advisory details: Ralf Spenneberg discovered that the USB driver for Clie devices in the Linux kernel did not properly validate the endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash). (CVE-2015-7566) Ralf Spenneberg discovered that the usbvision driver in the Linux kernel did not properl

    The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01, allows local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721.

    CVE-2016-0821

    The LIST_POISON feature in include/linux/poison.h in the Linux kernel before 4.3, as used in Android 6.0.1 before 2016-03-01, does not properly consider the relationship to the mmap_min_addr value, which makes it easier for attackers to bypass a poison-pointer protection mechanism by triggering the use of an uninitialized list entry, aka Android internal bug 26186802, a different vulnerability than CVE-2015-3636.

    linux-lts-utopic regression

    USN-2909-1 fixed vulnerabilities in the Ubuntu 14.10 Linux kernel backported to Ubuntu 14.04 LTS. An incorrect locking fix caused a regression that broke graphics displays for Ubuntu 14.04 LTS guests running the Ubuntu 14.10 backport kernel within VMWare virtual machines. This update fixes the problem. We apologize for the inconvenience. Original advisory details: halfdog discovered that OverlayFS, when mounting on top of a FUSE mount, incorrectly propagated file attributes, including setuid. A local unprivileged attacker could use this to gain privileges. (CVE-2016-1576) halfdog discovered that OverlayFS in the Linux kernel incorrect

    CVE-2016-0723

    Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call.

    CVE-2015-8709

    kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor states "there is no kernel bug here.

    CVE-2015-8575

    The sco_sock_bind function in net/bluetooth/sco.c in the Linux kernel before 4.3.4 does not verify an address length, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application.

    CVE-2015-7566

    The clie_5_attach function in drivers/usb/serial/visor.c in the Linux kernel through 4.4.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a bulk-out endpoint.
