Vulnerability title: Invalid Pointer Dereference In VMware Workstation and Player
|Affected version:||VMware WorkStation v10.0.1 build-1379776 and VMware Player v6.0.1 build-1379776|
|Reported by:||Kyriakos Economou|
The vmx86.sys (32 & 64-bit) kernel mode driver shared by various VMware Windows products such as VMware Workstation and VMWare Player, allows a local attacker to kill the host system through a Blue Screen of Death by sending a specific IOCTL code with a 3 bytes, or larger, input buffer.
The Blue Screen is triggered because the vulnerable function doesn’t check if a pointer to a memory page is valid or not, thus causing a memory access violation by trying to read from an unallocated memory page.
This vulnerability causes Denial of Service because of an Invalid Pointer Dereference.
The proof of concept exploit is available.
