Descriptions

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.

Multiple vulnerabilities have been found in Xpdf, the worst of which could result in denial of service. Versions greater than or equal to 4.05 are affected.
