CVE-2023-3044 is a low-severity flaw (CVSS 3.3) affecting xpdf. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
