The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3923-1 advisory.

    Michael Hanselmann discovered that QEMU incorrectly handled the Media Transfer Protocol (MTP). An attacker     inside the guest could use this issue to read or write arbitrary files and cause a denial of service, or     possibly execute arbitrary code. This issue only affected Ubuntu 18.10. (CVE-2018-16867)

    Michael Hanselmann discovered that QEMU incorrectly handled the Media Transfer Protocol (MTP). An attacker     inside the guest could use this issue to read arbitrary files, contrary to expectations. This issue only     affected Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-16872)

    Zhibin Hu discovered that QEMU incorrectly handled the Plan 9 File System support. An attacker inside the     guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2018-19489)

    Li Quang and Saar Amar discovered multiple issues in the QEMU PVRDMA device. An attacker inside the guest     could use these issues to cause a denial of service, or possibly execute arbitrary code. This issue only     affected Ubuntu 18.10. These issues were resolved by disabling PVRDMA support in Ubuntu 18.10.
    (CVE-2018-20123, CVE-2018-20124, CVE-2018-20125, CVE-2018-20126, CVE-2018-20191, CVE-2018-20216)

    Michael Hanselmann discovered that QEMU incorrectly handled certain i2c commands. A local attacker could     possibly use this issue to read QEMU process memory. This issue only affected Ubuntu 18.04 LTS and Ubuntu     18.10. (CVE-2019-3812)

    It was discovered that QEMU incorrectly handled the Slirp networking back-end. An attacker inside the     guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute     arbitrary code on the host. In the default installation, when QEMU is used with libvirt, attackers would     be isolated by the libvirt AppArmor profile. (CVE-2019-6778)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4556 advisory.

  - A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in     usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest     device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS     scenario OR possibly lead to code execution on the host. (CVE-2018-16867)

  - hw/rdma/vmw/pvrdma_main.c in QEMU does not implement a read operation (such as uar_read by analogy to     uar_write), which allows attackers to cause a denial of service (NULL pointer dereference).
    (CVE-2018-20191)

  - A flaw was found in qemu Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and     usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying     filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical     TOCTTOU problem. An attacker with write access to the host filesystem shared with a guest can use this     property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU     process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS.
    (CVE-2018-16872)

  - hw/rdma/rdma_backend.c in QEMU allows guest OS users to trigger out-of-bounds access via a PvrdmaSqWqe     ring element with a large num_sge value. (CVE-2018-20124)

  - QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and
    -1 is mishandled). (CVE-2018-20216)

  - hw/rdma/vmw/pvrdma_cmd.c in QEMU allows attackers to cause a denial of service (NULL pointer dereference     or excessive memory allocation) in create_cq_ring or create_qp_rings. (CVE-2018-20125)

  - hw/rdma/vmw/pvrdma_cmd.c in QEMU allows create_cq and create_qp memory leaks because errors are     mishandled. (CVE-2018-20126)

  - pvrdma_realize in hw/rdma/vmw/pvrdma_main.c in QEMU has a Memory leak after an initialisation error.
    (CVE-2018-20123)

  - In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow. (CVE-2019-6778)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for qemu fixes the following issues :

Remove a backslash '\' escape character from 80-qemu-ga.rules (bsc#1153358) Unlike sles 15 or newer guests, The udev rule file of qemu guest agent in sles 12 sp4 or newer guest only needs one escape character.
