Apple Updates Airport Drivers

Very interesting. As I stated over a week ago, all the hard headed Mac users that were in deep denial can now rest easy, know that buffer overflows exist in the Airport wireless drivers.

It is amazing how little respect researchers get when they attempt to protect the people in the end put them down. Will we see article in the media that reverse what they said before? Most likely not....

Watch the SANS page for update on this issue..

TITLE:
Apple Airport Buffer Overflow and Integer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA22068

VERIFY ADVISORY:
http://secunia.com/advisories/22068/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
From remote

OPERATING SYSTEM:
Apple Macintosh OS X
http://secunia.com/product/96/

DESCRIPTION:
Some vulnerabilities have been reported in AirPort, which can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system.

1) Two boundary errors exist in the handling of malformed wireless network frames. These can be exploited to cause a stack-based buffer overflow by sending a malicious frame to the system, and may allow arbitrary code execution with system privileges.

The vulnerability affects the following products equipped with
wireless:
* Power Mac
* PowerBook
* iBook
* iMac
* Mac Pro
* Xserve
* PowerPC-based Mac mini

2) A boundary error exists in the AirPort wireless driver's handling of scan cache updates. This can be exploited to cause a buffer overflow by sending a malicious frame to the system and may lead to a system crash, privilege elevation, or execution of arbitrary code with system privileges.

3) An integer overflow exist in the AirPort wireless drivers API for third-party software, which may lead to a buffer overflow in applications using the API. This can be exploited to cause a buffer overflow by sending a malicious frame to the system and could crash the application or lead to arbitrary code execution with privileges of the user running the application.

Vulnerabilities #2 and #3 affect Intel-based Mac mini, MacBook, and MacBook Pro equipped with wireless and does not affect systems prior to Mac OS X v10.4.

SOLUTION:
Apply Security Update 2006-005 or AirPort Update 2006-001:

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
