Microsoft PowerPoint Memory Corruption Vulnerability

-

Description


naveed has discovered a vulnerability in Microsoft PowerPoint, which potentially can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the application using data taken directly from a PowerPoint presentation file as a pointer when saving or closing the presentation. This can be exploited to corrupt memory and manipulate the program flow in various ways.

Successful exploitation crashes the application and arbitrary code execution may potentially also be possible, but has not currently been proven.

The vulnerability has been confirmed on Windows XP SP2 with a fully patched PowerPoint 2003. Other versions may also be affected.

NOTE: Two other issues, which can be exploited to crash the application, have also been reported.


Solution:
Do not open untrusted Office documents.
