Reimar Döffinger	b08edb2268	check that csize in ff_lzw_decode_init is < LZW_MAXBITS, <= is not enough and might read outside the prefix array Originally committed as revision 14214 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	0cb7f8a260	check input validity, this prevents a few variables from reachin odd values which might have lead to out of array writes and thus might have been exploitable Originally committed as revision 8522 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	5f01beb548	move eob_reached logic into ff_lzw_decode_tail() which simplifies the code, avoids some checks in the innermost loop and also gets rid of the controversal break while hopefully retaining the last byte in a valid bytestream, invalid bytestreams still can have very significant overread Originally committed as revision 8517 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
