Mtp-Target Server Memory Corruption Vulnerability

The Mtp-Target server is prone to a memory corruption vulnerability. The issue exists because a comparison fails to ensure that an integer value parameter retrieved from a client is signed. A check is made to ensure that the user-supplied value is less than 1000000 bytes. If the value passed is FFFFFFFFh, it is interpreted as a signed -1 and the check passes. The value is later used as an unsigned integer in a memory allocation operation. An allocation of 4.29 GB of data is attempted and the service crashes.

Mitigation:

Ensure that the user-supplied value is properly validated and that the value is treated as a signed integer.
