A heap-based buffer overflow vulnerability allows an authorized attacker to overflow memory buffers and execute code with elevated privileges, potentially compromising the entire system or gaining administrative control.
Technical details
A heap-based buffer overflow exists in the Volume Manager Driver, a privileged Windows kernel component. The vulnerability requires an authorized user on the system but allows privilege escalation through memory corruption. The attack vector is local; an attacker with valid credentials can trigger the overflow and gain elevated system privileges.
