Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel 2.6.28.4 (Operating System). Affected by this vulnerability is the function shm_get_stat. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. The summary by CVE is:

The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel before 2.6.28.5, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program.

The bug was discovered 02/12/2009. The weakness was released 03/09/2009 (Website). It is possible to read the advisory at xforce.iss.net. This vulnerability is known as CVE-2009-0859 since 03/09/2009. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 74 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 38668 (Debian DSA-1787-1 : linux-2.6.24 - denial of service/privilege escalation/information leak), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165644 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2009:028)).

Upgrading eliminates this vulnerability. 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 (49229), Tenable (38668), SecurityFocus (BID 34020†), OSVDB (52755†) and Secunia (SA34981†).
