CVE-2023-3044

An excessively large PDF page size (found in fuzz testing, unlikely in normal PDF files) can result in a divide-by-zero in Xpdf's text extraction code. This is related to CVE-2022-30524, but the problem here is caused by a very large page size, rather than by a very large character coordinate.

CVE-2023-2662

In Xpdf 4.04 (and earlier), a bad color space object in the input PDF file can cause a divide-by-zero.

In Xpdf 4.04 (and earlier), a PDF object loop in the embedded file tree leads to infinite recursion and a stack overflow.

CVE-2023-2663
