  "title": "pypdf: pypdf is an open source, pure-python PDF library",
  "description": "pypdf is an open source, pure-python PDF library. In affected versions an attacker may craft a PDF which leads to an infinite loop if \u0060__parse_content_stream\u0060 is executed. That is, for example, the case if the user extracted text from such a PDF. This issue was introduced in pull request #969 and resolved in pull request #1828. Users are advised to upgrade. Users unable to upgrade may modify the line \u0060while peek not in (b\u0022\\r\u0022, b\u0022\\n\u0022)\u0060 in \u0060pypdf/generic/_data_structures.py\u0060 to \u0060while peek not in (b\u0022\\r\u0022, b\u0022\\n\u0022, b\u0022\u0022)\u0060.",
