Technical Description

Two vulnerabilities have been identified in Microsoft Office Visio, which could be exploited by remote attackers to cause a denial of service or take complete control of an affected system.

The first issue is caused by a memory corruption error when handling object header data while opening Visio files, which could be exploited by attackers to crash an affected application or execute arbitrary code by tricking a user into opening a specially crafted Visio file.

The first issue is caused due to the application not properly validating memory allocations when loading specially crafted .DXF files from disk into memory, which could be exploited by attackers to crash an affected application or execute arbitrary code by tricking a user into opening a specially crafted file.

Note: DXF files are not registered by Visio by default.
