Description Vipul Nair 2026-07-20 10:08:36 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

pypdf is a free and open-source pure-python PDF library. Prior to 6.13.0, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires extracting the text in layout mode. This vulnerability is fixed in 6.13.0.

Version 6.14.2 is in rawhide.

For Fedora 44/43, I'm reluctant to upgrade them since it would be upgrading 2 major versions (from 4.2.0 to 6.14.2) in a stable release.
