Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    involving the number of link endpoint list descriptors
    (bsc#1028184)

  - CVE-2016-9603: A privileged user within the guest VM
    could have caused a heap overflow in the device model
    process, potentially escalating their privileges to that
    of the device model process (bsc#1028656)

  - CVE-2017-7718: hw/display/cirrus_vga_rop.h allowed local
    guest OS privileged users to cause a denial of service

    a privileged user inside guest to leak host memory
    resulting in DoS (bsc#1042801).

  - CVE-2017-8380: The MegaRAID SAS 8708EM2 Host Bus Adapter

    (bsc#1037336).

  - CVE-2016-9602: The VirtFS host directory sharing via
    Plan 9 File System(9pfs) support was vulnerable to an
    improper link following issue which allowed a privileged
    user inside guest to access host file system beyond the
    shared folder and potentially escalating their
    privileges on a host (bsc#1020427).

  - CVE-2017-7471: The VirtFS host directory sharing via
    Plan 9 File System(9pfs) support was vulnerable to an
    improper access control issue which allowed a privileged
    user inside guest to access host file system beyond the
    shared folder and potentially escalating their
    privileges on a host (bsc#1034866).

  - Fix privilege escalation in TCG mode of QEMU. This is
    not considered a security issue by the upstream project,
    but is included as additional hardening (bsc#1030624)

  - Fix potential DoS in virtfs

  - CVE-2016-10028: The Virtio GPU Device emulator support
    was vulnerable to an out of bounds memory access issue

    on a host, resulting in DoS (bsc#1017084, bsc#1016503)

  - CVE-2016-10029: The Virtio GPU Device emulator support
    was vulnerable to an OOB read issue allowing a guest
    user to crash the Qemu process instance resulting in Dos
    (bsc#1017081, bsc#1016504)

  - CVE-2017-5579: The 16550A UART serial device emulation
    support was vulnerable to a memory leakage issue
    allowing a privileged user to cause a DoS and/or
    potentially crash the Qemu process on the host
    (bsc#1021741)

  - CVE-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter
    emulation support was vulnerable to a NULL pointer
    dereference issue which allowed a privileged user inside
    guest to crash the Qemu process on the host resulting in
    DoS (bsc#1043296).

This non-security issue was fixed :

  - Enable MONITOR/MWAIT support for guests (bsc#1031142)

    privileges on a host (bsc#1020427).

  - CVE-2017-7471: The VirtFS host directory sharing via
    Plan 9 File System(9pfs) support was vulnerable to an

    user inside guest to access host file system beyond the
    shared folder and potentially escalating their
    privileges on a host (bsc#1034866).

    (bsc#1021741)

  - CVE-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter
    emulation support was vulnerable to a NULL pointer
    dereference issue which allowed a privileged user inside
    guest to crash the Qemu process on the host resulting in
    DoS (bsc#1043296).

The update package also includes non-security fixes. See advisory for
details.
