Detailsinfo

A vulnerability classified as critical was found in Linux Kernel (Operating System). This vulnerability affects the function kunmap. 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. CVE summarizes:

The fuse_ioctl_copy_user function in the ioctl handler in fs/fuse/file.c in the Linux kernel 2.6.29-rc1 through 2.6.30.y uses the wrong variable in an argument to the kunmap function, which allows local users to cause a denial of service (panic) via unknown vectors.

The issue has been introduced in 03/24/2009. The weakness was disclosed 12/24/2009 by David Shaw (Website). The advisory is shared for download at redhat.com. This vulnerability was named CVE-2009-4410. The exploitation appears to be easy. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 275 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 43594 (Fedora 11 : kernel-2.6.30.10-105.fc11 (2009-13694)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Tenable (43594), SecurityFocus (BID 37453†), OSVDB (61335†), Secunia (SA37928†) and Vulnerability Center (SBV-25704†). Once again VulDB remains the best source for vulnerability data.
