Description

Description

Microsoft Windows Local Descriptor Table programming interface is prone to a privilege-escalation vulnerability. A local attacker may be able to create a malicious entry in the Local Descriptor Table. This entry may point into protected memory. Since this memory space is reserved for kernel operations, the attacker will likely exploit this condition to execute arbitrary code with elevated privileges.
