CVE-2010-3014

Status Candidate

Overview

The Coda filesystem kernel module, as used in NetBSD and FreeBSD, when Coda is loaded and Venus is running with /coda mounted, allows local users to read sensitive heap memory via a large out_size value in a ViceIoctl struct to a Coda ioctl, which triggers a buffer over-read.

Posted Aug 17, 2010
Authored by Dan Rosenberg | Site vsecurity.com

Virtual Security Research, LLC. Security Advisory - VSR identified a vulnerability in the Coda filesystem kernel module, as implemented for FreeBSD and NetBSD. By sending a specially crafted ioctl request to a mounted Coda filesystem, an unprivileged local user could read large portions of kernel heap memory, leading to the disclosure of potentially sensitive information.
