Detailsinfo

A vulnerability has been found in Apple Mac OS X 10.9.5/10.10/10.10.1/10.10.2/10.10.3 (Operating System) and classified as problematic. Affected by this vulnerability is some unknown functionality of the component Temp File Handler. The manipulation with an unknown input leads to a symlink vulnerability. The CWE definition for the vulnerability is CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. As an impact it is known to affect integrity, and availability. The summary by CVE is:

kextd in kext tools in Apple OS X before 10.10.4 allows attackers to write to arbitrary files via a crafted app that conducts a symlink attack.

The weakness was published 06/30/2015 by Emil Kvarnhammar with Zero Day Initiative as HT204942 as confirmed advisory (Website). The advisory is shared at support.apple.com. The public release has been coordinated with Apple. This vulnerability is known as CVE-2015-3708 since 05/07/2015. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Technical details are unknown but an exploit is available.

It is declared as highly functional. The vulnerability scanner Nessus provides a plugin with the ID 84488 (Mac OS X 10.10.x < 10.10.4 Multiple Vulnerabilities (GHOST) (Logjam)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 123680 (Apple Mac OS X v10.10.4 and Security Update 2015-005 Not Installed (APPLE-SA-2015-06-30-2)).
