Detailsinfo

A vulnerability was found in Apple Mac OS X 10.3.9 (Operating System) and classified as critical. This issue affects an unknown code of the component CoreFoundation. 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 confidentiality, integrity, and availability. The summary by CVE is:

Integer underflow in CoreFoundation in Apple Mac OS X 10.3.9 and 10.4.6 allows context-dependent attackers to execute arbitrary code via unspecified vectors involving conversions from string to file system representation within (1) CFStringGetFileSystemRepresentation or (2) getFileSystemRepresentation:maxLength:withPath in NSFileManager, and possibly other similar API functions.

The bug was discovered 05/11/2006. The weakness was shared 05/08/2006 by Brent Simmons (McAfee) with McAfee AVERT Labs (Website). The advisory is shared at us-cert.gov.
