CVE-2016-9447

In GStreamer's gst-plugins-good, a heap-based out-of-bounds read of 4 bytes occurs when parsing FLAC audio stream headers embedded in Matroska or WebM container files. A boundary check does not account for the full size of the copied data, allowing a small read past the end of the allocated buffer. An attacker can exploit this by crafting a malicious Matroska or WebM file and tricking a user into opening it.

Multiple use-after-free vulnerabilities in the gst_mini_object_unref, gst_tag_list_unref, and 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.

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

The gst_date_time_new_from_iso8601_string function in GStreamer before version 1.10.3 allows remote attackers to cause a denial of service via a malformed datetime string, leading to an out-of-bounds heap read.

The vmnc decoder in gstreamer does not initialize the render canvas, allowing remote attackers to obtain sensitive information. This is demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.

Integer overflow in the vmnc decoder in gstreamer allows remote attackers to cause a denial of service (crash) via large width and height values, which triggers a buffer overflow.

Off-by-one error in the gst_h264_parse_set_caps function in GStreamer before version 1.10.2 allows remote attackers to have unspecified impact via a crafted file, leading to an out-of-bounds read.

The FLIC decoder in GStreamer before 1.10.2 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via a crafted series of skip and count pairs.

Use-After-Free vulnerability in GStreamer rtpsbcdepay allows remote code execution. Lack of validating object existence before operations leads to use-after-free. An attacker can leverage this to execute code in the context of the current process.

Heap-based buffer overflow in GStreamer PNG file parsing allows remote code execution. Lack of proper length validation before copying data to heap buffer leads to overflow. User interaction is required, such as visiting a malicious page or opening a malicious file.
