"The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2017-2060 advisory.

  - The gst_aac_parse_sink_setcaps function in gst/audioparsers/gstaacparse.c in gst-plugins-good in GStreamer
    before 1.10.3 allows remote attackers to cause a denial of service (invalid memory read and crash) via a
    crafted audio file. (CVE-2016-10198)

  - The gst_decode_chain_free_internal function in the flxdex decoder in gst-plugins-good in GStreamer before
    1.10.2 allows remote attackers to cause a denial of service (invalid memory read and crash) via an invalid
    file, which triggers an incorrect unref call. (CVE-2016-9810)

  - The windows_icon_typefind function in gst-plugins-base in GStreamer before 1.10.2, when G_SLICE is set to
    always-malloc, allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted ico
    file. (CVE-2016-9811)

  - The gst_avi_demux_parse_ncdt function in gst/avi/gstavidemux.c in gst-plugins-good in GStreamer before
    1.10.3 allows remote attackers to cause a denial of service (out-of-bounds heap read) via vectors
    involving ncdt tags. (CVE-2017-5841)

  - The html_context_handle_element function in gst/subparse/samiparse.c in gst-plugins-base in GStreamer
    before 1.10.3 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted SMI
    file, as demonstrated by OneNote_Manager.smi. (CVE-2017-5842)

  - Multiple use-after-free vulnerabilities in the (1) gst_mini_object_unref, (2) gst_tag_list_unref, and (3)
    gst_mxf_demux_update_essence_tracks functions in GStreamer before 1.10.3 allow remote attackers to cause a
    denial of service (crash) via vectors involving stream tags, as demonstrated by 02785736.mxf.
    (CVE-2017-5843)

  - The gst_ps_demux_parse_psm function in gst/mpegdemux/gstmpegdemux.c in gst-plugins-bad in GStreamer allows
    remote attackers to cause a denial of service (invalid memory read and crash) via vectors involving PSM
    parsing. (CVE-2017-5848)

  - The qtdemux_tag_add_str_full function in gst/isomp4/qtdemux.c in gst-plugins-good in GStreamer before
    1.10.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted
    tag value. (CVE-2016-10199)

  - The vmnc decoder in the gstreamer does not initialize the render canvas, which allows remote attackers to
    obtain sensitive information as demonstrated by thumbnailing a simple 1 frame vmnc movie that does not
    draw to the allocated render canvas. (CVE-2016-9446)

  - The gst_riff_create_audio_caps function in gst-libs/gst/riff/riff-media.c in gst-plugins-base in GStreamer
    before 1.10.3 allows remote attackers to cause a denial of service (floating point exception and crash)
    via a crafted video file. (CVE-2017-5837)

  - The gst_date_time_new_from_iso8601_string function in gst/gstdatetime.c in GStreamer before 1.10.3 allows
    remote attackers to cause a denial of service (out-of-bounds heap read) via a malformed datetime string.
    (CVE-2017-5838)

  - The gst_riff_create_audio_caps function in gst-libs/gst/riff/riff-media.c in gst-plugins-base in GStreamer
    before 1.10.3 does not properly limit recursion, which allows remote attackers to cause a denial of
    service (stack overflow and crash) via vectors involving nested WAVEFORMATEX. (CVE-2017-5839)

  - The qtdemux_parse_samples function in gst/isomp4/qtdemux.c in gst-plugins-good in GStreamer before 1.10.3
    allows remote attackers to cause a denial of service (out-of-bounds heap read) via vectors involving the
    current stts index. (CVE-2017-5840)

  - The gst_riff_create_audio_caps function in gst-libs/gst/riff/riff-media.c in gst-plugins-base in GStreamer
    before 1.10.3 allows remote attackers to cause a denial of service (floating point exception and crash)
    via a crafted ASF file. (CVE-2017-5844)

  - The gst_avi_demux_parse_ncdt function in gst/avi/gstavidemux.c in gst-plugins-good in GStreamer before
    1.10.3 allows remote attackers to cause a denial of service (invalid memory read and crash) via a ncdt
    sub-tag that goes behind the surrounding tag. (CVE-2017-5845)
