CVE-2023-3044

Status: ModifiedLow (3.3)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
