Detailsinfo

A vulnerability was found in Linux Kernel 2.6.23 (Operating System). It has been rated as critical. This issue affects the function hfsplus_find_cat. 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 availability. The summary by CVE is:

Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.

The bug was discovered 10/15/2008. The weakness was presented 11/05/2008 by Eric Sesterhenn (Website). The advisory is shared at openwall.com. The identification of this vulnerability is CVE-2008-4933 since 11/05/2008. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 393 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 67800 (Oracle Linux 5 : kernel (ELSA-2009-0264)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165629 (SUSE Enterprise Linux Security Update for Kernel (SUSE-SA:2009:008)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 4 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (46405), Tenable (67800), SecurityFocus (BID 32093†), OSVDB (49706†) and Secunia (SA32510†). See VDB-45344, VDB-45132, VDB-45061 and VDB-44962 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
