Vulnerability CVE-2010-3014


Published: 2010-08-20   Modified: 2012-02-13

Description:
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.
