2016-01-15mjpegdec: extend check for incompatible values of s->rgb and s->lsAndreas Cadhalpun
This can happen if s->ls changes from 0 to 1, but picture allocation is skipped due to s->interlaced. In that case ff_jpegls_decode_picture could be called even though the s->picture_ptr frame has the wrong pixel format and thus a wrong linesize, which results in a too small zero buffer being allocated. This fixes an out-of-bounds read in ls_decode_line.

2015-12-07mjpegdec: consider chroma subsampling in size checkAndreas Cadhalpun
If the chroma components are subsampled, smaller buffers are allocated for them. In that case the maximal block_offset for the chroma components is not as large as for the luma component. This fixes out of bounds writes causing segmentation faults or memory corruption.
