      "value": "eml_parser serves as a python module for parsing eml files and returning various information found in the e-mail as well as computed information. Prior to 3.0.1, EmlParser.get_raw_body_text() recurses unconditionally for every nested message/rfc822 attachment without any depth limit. An attacker who can supply a badly crafted EML file with approximately 120 nested message/rfc822 parts triggers an unhandled RecursionError and aborts parsing of the message. A 12 KB EML file is enough to crash a worker. Though this causes the parser to crash, it is an unlikely scenario as the suggested EML that crashes the parser would not pass basic RFC compliance tests. This vulnerability is fixed in 3.0.1."

      "value": "eml_parser sirve como un m\u00f3dulo de Python para analizar archivos eml y devolver diversa informaci\u00f3n encontrada en el correo electr\u00f3nico, as\u00ed como informaci\u00f3n calculada. Antes de la versi\u00f3n 3.0.1, EmlParser.get_raw_body_text() recurre incondicionalmente para cada adjunto anidado de tipo message/rfc822 sin ning\u00fan l\u00edmite de profundidad. Un atacante que puede proporcionar un archivo EML malformado con aproximadamente 120 partes anidadas de tipo message/rfc822 activa un RecursionError no manejado y aborta el an\u00e1lisis del mensaje. Un archivo EML de 12 KB es suficiente para bloquear un worker. Aunque esto causa que el analizador se bloquee, es un escenario poco probable ya que el EML sugerido que bloquea el analizador no pasar\u00eda las pruebas b\u00e1sicas de cumplimiento de RFC. Esta vulnerabilidad est\u00e1 corregida en la versi\u00f3n 3.0.1."
