Description:
--------------------------------------------------------------------------------
Bugtraq id: 57249
Cve id: CVE-2012-6429
 
Samsung Kies connects your pc to your phone so that you can easily synchronize data and find new software.
 
The cause of the vulnerability is that the PrepareSync () method in the ActiveX control SyncService. dll does not check the input data. Remote attackers can pass any value to the "password" parameter of the PrepareSync () method to trigger an ACCESS_VIOLATION exception. This vulnerability can be exploited to successfully rewrite the EIP register and SEH records.
 
SyncService. dll has a GUID of {EA8A3985-F9DF-4652-A255-E4E7772AFCA8} and the default location is "C: \ Program Files \ Samsung \ Kies \ External \ DeviceModules \ SyncService. dll ".
