Описание

Microsoft has become aware of limited targeted Windows 7 based attacks that could leverage un-patched vulnerabilities in the Adobe Type Manager Library, and is providing the following guidance to help reduce customer risk until the security update is released. We appreciate the efforts of our industry partners and are complying with a 7-day timeline for disclosing information regarding these limited attacks.

Two remote code execution vulnerabilities exist in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially-crafted multi-master font — Adobe Type 1 PostScript format.

There are multiple ways an attacker could exploit the vulnerability, such as convincing a user to open a specially crafted document or viewing it in the Windows Preview pane.

Microsoft is aware of this vulnerability and working on a fix. Updates that address security vulnerabilities in Microsoft software are typically released on Update Tuesday, the second Tuesday of each month. This predictable schedule allows for partner quality assurance and IT planning, which helps maintain the Windows ecosystem as a reliable, secure choice for our customers. The operating system versions that are affected by this vulnerability are listed below. Please see the mitigation and workarounds for guidance on how to reduce the risk.

Please Note: The threat is low for those systems running Windows 10 due to mitigations that were put in place with the first version released in 2015.

Please see the mitigation section for details. Microsoft is not aware of any attacks against the Windows 10 platform. The possibility of remote code execution is negligible and elevation of privilege is not possible. We do not recommend that IT administrators running Windows 10 implement the workarounds described below.

Microsoft recommends upgrading to the Windows 10 family of clients and servers.
