Detailsinfo

A vulnerability has been found in NetBSD up to 2.0.2 (Operating System) and classified as problematic. Affected by this vulnerability is the function ioctl of the component Sourd Driver. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

The (1) clcs and (2) emuxki drivers in NetBSD 1.6 through 2.0.2 allow local users to cause a denial of service (kernel crash) by using the set-parameters ioctl on an audio device to change the block size and set the pause state to "unpaused" in the same ioctl, which causes a divide-by-zero error.

The bug was discovered 06/13/2005. The weakness was shared 07/01/2005 by Ignatios Souvatzis and Yamamoto Takashi (Website). It is possible to read the advisory at ftp.netbsd.org. This vulnerability is known as CVE-2005-2134 since 07/05/2005. The attack needs to be initiated within the local network. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known.

After even before and not, there has been an exploit disclosed. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 18 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 2.0.3 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at netbsd.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the databases at X-Force (21526), SecurityFocus (BID 14122†), OSVDB (17681†), Secunia (SA15874†) and SecurityTracker (ID 1014348†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
