VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

A time of check time of use (TOCTOU) vulnerability exists in VMware ESXi, which the affected products use. Exploitation of the vulnerability can allow a threat actor with local administrative privileges to execute code as the virtual machine's VMX process running on the host. A code execution vulnerability exists in VMware ESXi, which the affected products use. Exploitation of the vulnerability can allow a threat actor with privileges within the VMX process trigger an arbitrary kernel write, leading to an escape of the sandbox. An out-of-bounds vulnerability exists in VMware ESXi, which the affected products use. Exploitation of the vulnerability can allow a threat actor with administrative privileges to leak memory from the vmx process.

Ein lokaler Angreifer kann mehrere Schwachstellen in VMware ESXi, VMware Workstation, VMware Fusion und VMware Cloud Foundation ausnutzen, um beliebigen Code auszuführen, erhöhte Rechte zu erlangen und vertrauliche Informationen preiszugeben.
