Description Dhananjay Arunesh 2019-07-09 03:50:22 UTC

In Xpdf 4.01.01, there is a heap-based buffer over-read in the function
JBIG2Stream::readTextRegionSeg() located at JBIG2Stream.cc. It can, for example,
be triggered by sending a crafted PDF document to the pdftoppm tool. It might
allow an attacker to cause Information Disclosure.
