Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel 2.6.28.2 (Operating System). This affects the function do_mmap_pgoff. The manipulation with an unknown input leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability. The summary by CVE is:

The do_mmap_pgoff function in mm/nommu.c in the Linux kernel before 2.6.31.6, when the CPU lacks a memory management unit, allows local users to cause a denial of service (OOPS) via an application that attempts to allocate a large amount of memory.

The issue has been introduced in 12/25/2008. The weakness was disclosed 11/16/2009 as confirmed git commit (GIT Repository). The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2009-3888 since 11/05/2009. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 326 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 43026 (Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : linux, linux-source-2.6.15 vulnerabilities (USN-864-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 195006 (Ubuntu Security Notification for Linux, Linux-source-2.6.15 Vulnerabilities (USN-864-1)).

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 (54211), Exploit-DB (10017), Tenable (43026), SecurityFocus (BID 36953†) and Vulnerability Center (SBV-24540†). The entry VDB-50657 is pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
