CVE-2015-2557

Desbordamiento de buffer en Microsoft Visio 2007 SP3 y 2010 SP2 permite a atacantes remotos ejecutar código arbitrario a través de datos UML manipulados en un documento Office, también conocido como 'Microsoft Office Memory Corruption Vulnerability'.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Visio. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within UML parsing. By providing a malformed Visio file, an attacker is able to cause data to be written outside of a normal buffer. An attacker could use this to execute arbitrary code under the context of the Visio process.
