====================================================================== 4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in Microsoft Office, which can be exploited by malicious people to compromise a user's system.

1) An input validation error in the TIFF Import/Export Graphic Filter when copying certain data can be exploited to cause a heap-based buffer overflow via a specially crafted TIFF image.

2) Another input validation error in the TIFF Import/Export Graphic Filter when copying certain data after having encountered a specific error can be exploited to cause a heap-based buffer overflow via a specially crafted TIFF image.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code when processing a TIFF image in an application using the graphics filter (e.g. opening the image in Microsoft Photo Editor or importing it into an Office document).

====================================================================== 5) Solution

Apply patches provided by MS10-105.
