HTTP: Microsoft Excel rtWindow1 Record Handling Code Execution

A memory corruption vulnerability exists in the way Microsoft Excel handles XLS files that contain invalid values within the rtWindow1 records. A remote attacker can exploit this vulnerability by persuading a target user to open a specially crafted XLS file, potentially causing arbitrary code to be injected and executed in the security context of the logged in user. An attack targeting this vulnerability can result in the injection and execution of code. If code execution is successful, the behaviour of the target will depend on the intention of the attacker. Any code injected will be executed within the security context of the currently logged in user. In the case of an unsuccessful code execution attack, Excel will terminate resulting in the loss of any unsaved data from the current session.

Extended Description

Microsoft Excel is prone to a remote code-execution vulnerability. Attackers may exploit this issue by enticing victims into opening a maliciously crafted Excel file (.xls). Successful exploits may allow attackers to execute arbitrary code with the privileges of the user running the application. This may facilitate a compromise of vulnerable computers. This issue was previously reported as a denial-of-service vulnerability, but has been updated to reflect new information.
