Descriptions

Microsoft Edge in Microsoft Windows 10 Gold, 1511, 1607, 1703, 1709, and Windows Server 2016 allows an attacker to obtain information to further compromise the user's system, due to how the Microsoft Edge PDF Reader handles objects in memory, aka "Microsoft Edge Information Disclosure Vulnerability".

Microsoft Edge en Microsoft Windows 10 Gold, 1511, 1607, 1703, 1709 y Windows Server 2016 permite que un atacante obtenga información para comprometer aun más la seguridad del sistema del usuario debido a la forma en la que el lector de PDF de Microsoft Edge gestiona objetos en la memoria. Esto también se conoce como "Microsoft Edge Information Disclosure Vulnerability".

This vulnerability allows remote attackers to disclose sensitive on vulnerable installations of Microsoft Windows PDF Library. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of JPEG2000 images in PDF documents. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
