KB4056897: Windows 7 and Windows Server 2008 R2 January 2018 Security Update (Meltdown)(Spectre)

High Nessus Plugin ID 105552

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4056897 or cumulative update 4056894. It is, therefore, affected by multiple vulnerabilities :

- An vulnerability exists within microprocessors utilizing speculative execution and indirect branch prediction, which may allow an attacker with local user access to disclose information via a side-channel analysis.
(CVE-2017-5715, CVE-2017-5753, CVE-2017-5754)

- An elevation of privilege vulnerability exists in Windows Adobe Type Manager Font Driver (ATMFD.dll) when it fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code and take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-0788)

- An information disclosure vulnerability exists in Windows Adobe Type Manager Font Driver (ATMFD.dll) when it fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could potentially read data that was not intended to be disclosed. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system. (CVE-2018-0754)

- A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user.
(CVE-2018-0762, CVE-2018-0772)

- An information disclosure vulnerability exists in the way that the Color Management Module (ICM32.dll) handles objects in memory. This vulnerability allows an attacker to retrieve information to bypass usermode ASLR (Address Space Layout Randomization) on a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability. (CVE-2018-0741)

- An information disclosure vulnerability exists in the Windows kernel that could allow an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (ASLR) bypass. An attacker who successfully exploited the vulnerability could retrieve the memory address of a kernel object. (CVE-2018-0747)

- An elevation of privilege vulnerability exists in the Microsoft Server Message Block (SMB) Server when an attacker with valid credentials attempts to open a specially crafted file over the SMB protocol on the same machine. An attacker who successfully exploited this vulnerability could bypass certain security checks in the operating system. (CVE-2018-0749)

- An elevation of privilege vulnerability exists in the way that the Windows Kernel API enforces permissions. An attacker who successfully exploited the vulnerability could impersonate processes, interject cross-process communication, or interrupt system functionality.
(CVE-2018-0748)

- A Win32k information disclosure vulnerability exists when the Windows GDI component improperly discloses kernel memory addresses. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2018-0750)

Solution

Apply Security Only update KB4056897 or Cumulative Update KB4056894.

Note: Due to a compatibility issue with some antivirus software products, it may not be possible to apply the required updates.
