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.
