CVE-2002-0766

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 ope...

CVE-2002-0820

FreeBSD kernel 4.6 and earlier closes the file descriptors 0, 1, and 2 after they have already been assigned to /dev/null when the descriptors reference procfs or linprocfs, which could allow local users to reuse the file descriptors in a setuid or setgid program to modify critical data and gain...

CVE-2002-0767

simpleinit on Linux systems does not close a read/write FIFO file descriptor before creating a child process, which allows the child process to cause simpleinit to execute arbitrary programs with root privileges...

CVE-2002-0767

The CVE-2002-0767 issue affects Linux systems running the simpleinit component. The root cause is that simpleinit does not close a read/write FIFO file descriptor before forking a child process. Consequently, the child process can cause simpleinit to execute arbitrary programs with root privilege...

CVE-2002-0572

FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 standard input, 1 standard output, or 2 standard error, which may then be reused by a called setuid process that intended to...

OpenBSD kernel fails to properly check closed file descriptors "0-2" when running setuid program

Overview The OpenBSD kernel does not adequately check file descriptors 0-2 prior to execing setuid binaries. Other OS kernels may be vulnerable as well. Description The OpenBSD kernel does not adequately check file descriptors 0-2 prior to execing setuid binaries. As a result, an attacker may be...

/ source: https://www.securityfocus.com/bid/4568/info It has been reported that BSD-based kernels do not check to ensure that the C library standard I/O file descriptors 0-2 are valid open files before execing setuid images. Consequently, I/O that are opened by a setuid process may be assigned fi...

CVE-2001-1047

Race condition in OpenBSD VFS allows local users to cause a denial of service kernel panic by 1 creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or 2 calling dup2 on a file descriptor in one process, then setting the descriptor to NU...
