Detailsinfo

A vulnerability was found in Linux Kernel up to 2.4.33.5 (Operating System). It has been rated as critical. Affected by this issue is an unknown code of the component Bluetooth CAPI. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Multiple buffer overflows in the cmtp_recv_interopmsg function in the Bluetooth driver (net/bluetooth/cmtp/capi.c) in the Linux kernel 2.4.22 up to 2.4.33.4 and 2.6.2 before 2.6.18.6, and 2.6.19.x, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via CAPI messages with a large value for the length of the (1) manu (manufacturer) or (2) serial (serial number) field.

The bug was discovered 12/17/2006. The weakness was disclosed 12/18/2006 by Marcel Holtmann with Kernel Team (Website). The advisory is available at kernel.org. This vulnerability is handled as CVE-2006-6106 since 11/24/2006. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are unknown but an exploit is available.

The exploit is available at bugzilla.redhat.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 36838 (CentOS 4 : kernel (CESA-2007:0014)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115509 (Red Hat Kernel Security Update (RHSA-2007:0014)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at kernel.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (30912), Tenable (36838), SecurityFocus (BID 21604†), OSVDB (31375†) and Secunia (SA24105†). The entries VDB-2551, VDB-2589, VDB-2647 and VDB-2661 are pretty similar. If you want to get best quality of vulnerability data, you may have to visit VulDB.
