Format string vulnerability in VMware Workstation 4.5.2 build-8848, if running with elevated privileges, might allow local users to execute arbitrary code via format string specifiers in command line arguments. NOTE: it is not clear if there are any default or typical circumstances under which VMware would be running with privileges beyond those already available to the attackers, so this might not be a vulnerability.

VMWare creates a temporary file vmware-log.USERNAME with insecure permissions, which allows local users to read or modify license information.

Buffer overflow in VMWare 1.0.1 for Linux via a long HOME environmental variable.

VMware Workstation 4.0.1 for Linux, build 5289 and earlier, allows local users to delete arbitrary files via a symlink attack.

vmware-config.pl in VMware for Linux, ESX Server 2.x, and Infrastructure 3 does not check the return code from a Perl chmod function call, which might cause an SSL key file to be created with an unsafe umask that allows local users to read or modify the SSL key.

Heap-based buffer overflow in the NAT networking components vmnat.exe and vmnet-natd in VMWare Workstation 5.5, GSX Server 3.2, ACE 1.0.1, and Player 1.0 allows remote authenticated attackers, including guests, to execute arbitrary code via crafted (1) EPRT and (2) PORT FTP commands.

VMware GSX Server 2.5.1 build 4968 and earlier, and Workstation 4.0 and earlier, allows local users to gain root privileges via certain enivronment variables that are used when launching a virtual machine session.

Unquoted Windows search path vulnerability in VMWare Workstation 5.0.0 build-13124 might allow local users to gain privileges via a malicious "program.exe" file in the C: folder.

VMWare 1.1.2 allows local users to cause a denial of service via a symlink attack.

VMware Workstation 4.0 for Linux allows local users to overwrite arbitrary files and gain privileges via "symlink manipulation."

VMware before 4.5.2.8848-r5 searches for gdk-pixbuf shared libraries using a path that includes the rrdharan world-writable temporary directory, which allows local users to execute arbitrary code.

vSockets information-disclosure vulnerability

VMware ESXi, Workstation, Fusion, and VMware Tools contains an information disclosure vulnerability due to the usage of an uninitialised memory in vSockets. A malicious actor with local administrative privileges on a virtual machine may be able to exploit this issue to leak memory from processes communicating with vSockets.

PVSCSI heap-overflow vulnerability

VMware ESXi, Workstation, and Fusion contain a heap-overflow vulnerability in the PVSCSI (Paravirtualized SCSI) controller 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. On ESXi, the exploitation is contained within the VMX sandbox and exploitable only with configurations that are unsupported. On Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.

Denial-of-Service Vulnerability

VMware ESXi, Workstation, and Fusion contain a denial-of-service vulnerability due to certain guest options. A malicious actor with non-administrative privileges within a guest operating system may be able to exploit this issue by exhausting memory of the host process leading to a denial-of-service condition.

VMXNET3 integer-overflow vulnerability

VMware ESXi, Workstation, and Fusion contain an integer-overflow vulnerability in the VMXNET3 virtual network adapter. A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host. Non VMXNET3 virtual adapters are not affected by this issue.

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, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to leak memory from the vmx process.

VMware ESXi (7.0 before ESXi70U1b-17168206, 6.7 before ESXi670-202011101-SG, 6.5 before ESXi650-202011301-SG), Workstation (15.x before 15.5.7), Fusion (11.x before 11.5.7) contain a use-after-free vulnerability in the XHCI USB controller. 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.

Information disclosure vulnerability

VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability in the UHCI USB controller. A malicious actor with administrative access to a virtual machine may be able to exploit this issue to leak memory from the vmx process.  

VMware ESXi (7.0 prior to ESXi70U1c-17325551), VMware Workstation (16.x prior to 16.0 and 15.x prior to 15.5.7), VMware Fusion (12.x prior to 12.0 and 11.x prior to 11.5.7) and VMware Cloud Foundation contain a denial of service vulnerability due to improper input validation in GuestInfo. A malicious actor with normal user privilege access to a virtual machine can crash the virtual machine's vmx process leading to a denial of service condition.
