  "description": "pypdf is a free and open-source pure-python PDF library. Prior to 6.7.3, an attacker who uses this vulnerability can craft a PDF which leads to the RAM being exhausted. This requires accessing the \u0060xfa\u0060 property of a reader or writer and the corresponding stream being compressed using \u0060/FlateDecode\u0060. This has been fixed in pypdf 6.7.3. As a workaround, apply the patch manually.",
