CVE-2025-62707 — pypdf affected by possible infinite loop when reading DCT inline images without EOF marker

Affected: py-pdf pypdf

pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3.
