CVE-2025-43718

Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor).

Summary		(es) Poppler 24.06.1 hasta 25.x antes de 25.04.0 permite el consumo de pila y un SIGSEGV a través de estructuras profundamente anidadas dentro de los metadatos (como GTS_PDFEVersion) de un documento PDF, por ejemplo, una expresión regular para una cadena pdfsubver larga. Esto ocurre en Dict::lookup, Catalog::getMetadata y funciones asociadas en PDFDoc, con recursión profunda en el ejecutor de expresiones regulares (std::__detail::_Executor).
