Heap-based buffer overflow in the qtdemux_parse_samples function in gst/qtdemux/qtdemux.c in GStreamer Good Plug-ins (aka gst-plugins-good) 0.10.9 through 0.10.11, and GStreamer Plug-ins (aka gstreamer-plugins) 0.8.5, might allow remote attackers to execute arbitrary code via crafted Time-to-sample (aka stts) atom data in a malformed QuickTime media .mov file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
