Description Marian Rehak 2019-05-24 07:41:46 UTC
An issue was discovered in Poppler 0.76.1. There is a heap-based buffer over-read in the function JPXStream::init in JPEG2000Stream.cc.

Affects: fedora-all [bug 1713585]

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.
