Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to the code doesn’t handle IP Options at all and simply removes them from the packet by using memmove and truncating the xDataLength field of the network buffer. A remote attacker can trigger memory corruption in usGenerateProtocolChecksum and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
