Vulnerability DetailsThe vulnerability is due to an integer overflow in the Microsoft Windows EOT component, the Embedded OpenType Font Engine, when parsing certain tables within specially crafted files and content containing embedded fonts. A remote attacker may exploit this issue by creating a file that contains a specially crafted EOT font embedded in the document and convincing the user to open or preview the file. Successful exploitation of this issue allows execution of arbitrary code once the malformed file is being opened or previewed on an affected system.
