vmware-hgfsmounter in VMware Open Virtual Machine Tools (aka open-vm-tools) 8.4.2-261024 and earlier attempts to append to the /etc/mtab file without first checking whether resource limits would interfere, which allows local users to trigger corruption of this file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089.

Security readout for executives and security teams

CVE-2011-1681 affects older open-vm-tools. A local user can make vmware-hgfsmounter corrupt /etc/mtab, a system file used for mount state tracking. The sources do not show remote exploitation or active exploitation. Business urgency depends on whether legacy Linux virtual machines still run affected open-vm-tools packages. Exposure is most likely on legacy Linux guest VMs running open-vm-tools 8.4.2-261024 or earlier, especially where local shell users exist. The provided affected-product metadata is incomplete. Treat this as a legacy exposure cleanup item, not an emergency, unless affected multi-user VMs remain in production. Prioritize patching or replacing old guest tools where local users are untrusted. Mitigation focus: Inventory Linux VMs for installed open-vm-tools packages and versions.; Apply VMware or Linux distribution updates that address CVE-2011-1681.; Review vendor advisories before assuming a fixed version..
