Multiple VMware products HGFS buffer overflow

vmware-hgfs-bo (42753) The risk level is classified as HighHigh Risk

Description:

Multiple VMware products are vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the implementation of the Host Guest File System (HGFS) shared folders feature. If the shared folders are enabled and at least one folder is shared, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the vmx process.
