CVE-2026-27628 not yet assigned priority: Debian including 2 source packages (pypdf, pypdf2), 6 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 4, resolved 2.
pypdf is a free and open-source pure-python PDF library. Prior to 6.7.2, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires reading the file. This has been fixed in pypdf 6.7.2. As a workaround, one may apply the patch manually.
