  1. CVE-2015-8552

    Mittel · CVSS 4.4EPSS 0,45%Korrektur verfügbar

    CVE-2015-8552

    The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks."

    CVE-2015-8551

    The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux pciback missing sanity checks."

    CVE-2016-3157

    The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access.

  4. CVE-2016-0821

    Hoch · CVSS 7.5EPSS 0,38%Korrektur verfügbar

    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.

  5. USN-2910-2

    Nicht bewertetKorrektur verfügbar

    linux-lts-vivid regression

    USN-2910-1 fixed vulnerabilities in the Ubuntu 15.04 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 15.04 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-2015-8787

    The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel before 4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604.

    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.
