Comment 2 Riccardo Schirone 2019-06-24 14:41:09 UTC

Upstream patch:
https://gitlab.freedesktop.org/poppler/poppler/commit/89a5367d49b2556a2635dbb6d48d6a6b182a2c6c

Comment 4 Riccardo Schirone 2019-06-24 16:51:56 UTC

It is possible to read and write beyond the limits of a buffer in the JPXStream::init() function in JPEG2000Stream.cc file, because the number of pixels in the image may not correspond to the width * height of the image. The patch checks that the number of pixels (priv->npixels) and the width * height values match.
