CVE-2002-0766 is a vulnerability of currently unknown severity. OpenBSD 2.9 through 3.1 allows local users to cause a denial of service (resource exhaustion) and gain root privileges by filling the kernel's file descriptor table and closing file descriptors 0, 1, or 2 before executing a privileged process, which is not properly handled when OpenBSD fails to open an alternate descriptor.. EPSS estimates a 0.59% chance of exploitation in the next 30 days.
