* mjpegdec: extend check for incompatible values of s->rgb and s->lsAndreas Cadhalpun2016-01-151-1/+2
| | | | | | | | | | | | | | | | | 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.
