Descriptions
The opj_dwt_decode_1* functions in dwt.c in OpenJPEG, as used in PDFium in Google Chrome before 47.0.2526.73, allow remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data that is mishandled during a discrete wavelet transform.
