CVE-2002-0766
HighSummary
OpenBSD versions 2.9 through 3.1 allow 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.
Risk Assessment
The organization may be vulnerable to attacks from local users who can exploit this vulnerability to gain unauthorized access to the system and cause a denial of service.
Recommendation
It is recommended to update the OpenBSD system to the latest version to mitigate this vulnerability and to monitor the system for unauthorized activities.
