Description Andrej Nemec 2016-11-15 08:49:56 UTC

A vulnerability was found in gstreamer-0.10. There is a near total lack of bounds checking on proposed ROM mappings. This applies to be the initial ROM load, as well as subsequent ROM bank switching. All of the handling for ROM mapping is in gst-plugins-bad/gst/nsf.c
