[Gnash-commit] [bug #37629] buffer overflow from Input::readSWFJpeg3

[Bastiaan Jacques]

Follow-up Comment #7, bug #37629 (project gnash):

The source of the problem is different than I thought. readSWFJpeg3() is
clearly written with a 3-bytes per pixel decoded image in mind, but in this
case libjpeg is decoding to a 4-byte per pixel format. In other words, the
following will fail if put inside readSWFJpeg3():

assert( j_in->getComponents() == 3);

The rest of the code, including the allocation, is done with this assumption
in mind.

Still left to discover is whether it is possible to include this JPEG data
into an AVM1 movie.
