Description
### Impact An attacker who uses this vulnerability can craft a PDF which leads to arbitrary image parsers being called. This requires loading an image which claims to use the `/DCTDecode` filter (JPEG data). Users which do not have the optional *Pillow* dependency installed in their environment are not affected. ### Patches This has been fixed in [pypdf==6.21.1](https://github.com/py-pdf/pypdf/releases/tag/6.21.1). ### Workarounds If you cannot upgrade yet, consider applying the changes from PR [#4222](https://github.com/py-pdf/pypdf/pull/4222).
