CVE-2007-1337 1 Vmware 1 Workstation 2018-10-16 7.8 HIGH N/A
The virtual machine process (VMX) in VMware Workstation before 5.5.4 does not properly read state information when moving from the ACPI sleep state to the run state, which allows attackers to cause a denial of service (virtual machine reboot) via unknown vectors.
CVE-2007-1069 1 Vmware 1 Workstation 2018-10-16 7.8 HIGH N/A
The memory management in VMware Workstation before 5.5.4 allows attackers to cause a denial of service (Windows virtual machine crash) by triggering certain general protection faults (GPF).
CVE-2007-1056 1 Vmware 1 Workstation 2018-10-16 7.2 HIGH N/A
VMware Workstation 5.5.3 build 34685 does not provide per-user restrictions on certain privileged actions, which allows local users to perform restricted operations such as changing system time, accessing hardware components, and stopping the "VMware tools service" service. NOTE: exploitation is simplified via (1) weak file permissions (Users = Read & Execute) for %PROGRAMFILES%\VMware; and weak registry key permissions (access by Users) for (2) vmmouse, (3) vmscsi, (4) VMTools, (5) vmx_svga, and (6) vmxnet in HKLM\SYSTEM\CurrentControlSet\Services\; which allows local users to perform various privileged actions outside of the guest OS by executing certain files under %PROGRAMFILES%\VMware\VMware Tools, as demonstrated by (a) VMControlPanel.cpl and (b) vmwareservice.exe.
