CVE-2019-9543

An issue was discovered in Poppler 0.74.0. A recursive function call, in
JBIG2Stream::readGenericBitmap() located in JBIG2Stream.cc, can be
triggered by sending a crafted pdf file to (for example) the pdfseparate
binary. It allows an attacker to cause Denial of Service (Segmentation
fault) or possibly have unspecified other impact. This is related to
JArithmeticDecoder::decodeBit.
