MS12-076: Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2720184) (Mac OS X)

high Nessus Plugin ID 62909

Synopsis

An application installed on the remote Mac OS X host is affected by multiple remote code execution vulnerabilities.

Description

The remote Mac OS X host is running a version of Microsoft Excel that is affected by the following vulnerabilities :

- A heap-based buffer overflow vulnerability exists due to the way the application handles memory when opening Excel files. (CVE-2012-1885)

- A memory corruption vulnerability exists due to the way the application handles memory when opening Excel files. (CVE-2012-1886)

- A use-after-free vulnerability exists due to the way the application handles memory when opening Excel files. (CVE-2012-1887)

- A stack-based buffer overflow vulnerability exists due to the way the application handles data structures while parsing Excel files. (CVE-2012-2543)

If an attacker can trick a user on the affected host into opening a specially crafted Excel file, it may be possible to leverage these issues to execute arbitrary code subject to the user's privileges.

Solution

Microsoft has released a set of patches for Office for Mac 2011 and Office 2008 for Mac.
