Detailsinfo

A vulnerability was found in Apple Mac OS X up to 10.4 (Operating System). It has been classified as critical. This affects an unknown functionality. The manipulation of the argument num_sels with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in the kernel in Apple Mac OS X 10.4 through 10.4.10 allows local users to execute arbitrary code via a large num_sels argument to the i386_set_ldt system call.

The bug was discovered 11/14/2007. The weakness was published 11/14/2007 by Ilja van Sprundel (Sean) with RISE Security (Website). The advisory is shared at us-cert.gov. This vulnerability is uniquely identified as CVE-2007-4684 since 09/05/2007. 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. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 28212 (Mac OS X < 10.4.11 Multiple Vulnerabilities (Security Update 2007-008)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context c. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115661 (Apple Mac OS X 10.4.11 Not Installed (APPLE-SA-2007-11-14)).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (38468), Exploit-DB (4624), Tenable (28212), SecurityFocus (BID 26444†) and OSVDB (40676†). Similar entries are available at VDB-1498, VDB-3185, VDB-3342 and VDB-3343. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
