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.

Rejected reason: DO NOT USE THIS CVE RECORD. ConsultIDs: CVE-2022-30524. Reason: This record is a duplicate of CVE-2022-30524. Notes: All CVE users should reference CVE-2022-30524 instead of this record. All references and descriptions in this record have been removed to prevent accidental usage.

There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.
