Descriptions

The CPDF_Document::GetPage function in fpdfapi/fpdf_parser/fpdf_parser_document.cpp in PDFium, as used in Google Chrome before 46.0.2490.71, does not properly perform a cast of a dictionary object, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document.

La función CPDF_Document::GetPage en fpdfapi/fpdf_parser/fpdf_parser_document.cpp en PDFium, como se utiliza en Google Chrome en versiones anteriores a 46.0.2490.71, no lleva a cabo correctamente una proyección de un objeto de diccionario, lo que permite a atacantes remotos provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de un documento PDF manipulado.

Chromium is an open-source web browser, powered by WebKit. Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to crash, execute arbitrary code, or disclose sensitive information when visited by the victim. All Chromium users should upgrade to these updated packages, which contain Chromium version 46.0.2490.71, which corrects these issues. After installing the update, Chromium must be restarted for the changes to take effect.
