NetBSD Security Advisory 2006-012

Description

NetBSD contains a flaw that may allow a local denial of service. The issue is triggered when a malicious user attempts to gather information on a non-existent alias of a network interface via the SIOCGIFALIAS ioctl, resulting in a NULL dereference in the kernel when the alias in question is not located. This will lead to a loss of availability for the platform.

Classification

Location: Local Access Required
Attack Type: Denial of Service
Impact: Loss of Availability
Disclosure: OSVDB Verified

Solution

Obtain fixed kernel sources, rebuild and install the new kernel, and reboot the system.

The fixed source may be obtained from the NetBSD CVS repository.
