CWE-369  (opens in a new tab)

How to fix?

Upgrade Alpine:3.21 xpdf to version 4.05-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xpdf package and not the xpdf package as distributed by Alpine. See How to fix? for Alpine:3.21 relevant fixed versions and status.

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.
