Detailsinfo

A vulnerability classified as critical was found in Linux Kernel 2.6.16.9 (Operating System). Affected by this vulnerability is the function pkt_find_dev_from_minor. The manipulation with an unknown input leads to a numeric error vulnerability. The CWE definition for the vulnerability is CWE-189. As an impact it is known to affect confidentiality, and availability. The summary by CVE is:

Integer signedness error in the pkt_find_dev_from_minor function in drivers/block/pktcdvd.c in the Linux kernel before 2.6.36-rc6 allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and system crash) via a crafted index value in a PKT_CTRL_CMD_STATUS ioctl call.

The issue has been introduced in 03/20/2006. The weakness was presented 10/04/2010 by Dan Rosenberg as confirmed git commit (GIT Repository). It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2010-3437. The exploitation appears to be easy. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known.

A public exploit has been developed by Jon Oberheide in ANSI C and been published even before and not after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1659 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 51614 (SuSE 11.1 Security Update : Linux kernel (SAT Patch Numbers 3760 / 3762 / 3763)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155569 (Oracle Linux 5 Unbreakable Enterprise Kernel Security and Bug Fix Update (ELSA-2010-2011)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.kernel.org.

The vulnerability is also documented in the databases at X-Force (62124), Exploit-DB (15150), Tenable (51614), SecurityFocus (BID 43551†) and OSVDB (68370†). See VDB-4176, VDB-55542, VDB-55538 and VDB-55535 for similar entries. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
