Detailsinfo

A vulnerability classified as problematic has been found in Apple Mac OS X up to 10.8.3 (Operating System). Affected is the function posix_spawn of the component XNU Kernel. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. CVE summarizes:

The posix_spawn system call in the XNU kernel in Apple Mac OS X 10.8.x does not properly validate the data for file actions and port actions, which allows local users to (1) cause a denial of service (panic) via a size value that is inconsistent with a header count field, or (2) obtain sensitive information from kernel heap memory via a certain size value in conjunction with a crafted buffer.

The weakness was presented 04/26/2013 by Stefan Esser with SektionEins GmbH as not defined article (Website). The advisory is available at antid0te.com. The vendor was not involved in the coordination of the public release. This vulnerability is traded as CVE-2013-3954 since 06/05/2013. Local access is required to approach this attack.
