Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel (Operating System). This affects the function invalidate_inode_pages2_range of the file mm/truncate.c. The manipulation with an unknown input leads to a integer coercion vulnerability. CWE is classifying the issue as CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. This is going to have an impact on availability. The summary by CVE is:

Integer overflow in the invalidate_inode_pages2_range function in mm/truncate.c in Linux kernel 2.6.11 to 2.6.14 allows local users to cause a denial of service (hang) via 64-bit mmap calls that are not properly handled on a 32-bit system.

The bug was discovered 11/23/2005. The weakness was released 11/25/2005 by LINUX (Website). The advisory is shared at kernel.org. This vulnerability is uniquely identified as CVE-2005-3808 since 11/25/2005. 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 268 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 20306 (Fedora Core 4 : kernel-2.6.14-1.1653_FC4 (2005-1138)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 3 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (24465), Exploit-DB (26811), Tenable (20306), SecurityFocus (BID 15846†) and OSVDB (22508†). Entries connected to this vulnerability are available at VDB-1817, VDB-27131 and VDB-27121. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
