AirPort Update 2006-001 and Security Update 2006-005
-
AirPort CVE-ID: CVE-2006-3507 Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Attackers on the wireless network may cause arbitrary code execution Description: Two separate stack buffer overflows exist in the AirPort wireless driver's handling of malformed frames. An attacker in local proximity may be able to trigger an overflow by injecting a maliciously-crafted frame into a wireless network. When the AirPort is on, this could lead to arbitrary code execution with system privileges. This issue affects Power Mac, PowerBook, iBook, iMac, Mac Pro, Xserve, and PowerPC-based Mac mini computers equipped with wireless. Intel-based Mac mini, MacBook, and MacBook Pro computers are not affected. There is no known exploit for this issue. This update addresses the issues by performing additional validation of wireless frames.

AirPort CVE-ID: CVE-2006-3508 Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Attackers on the wireless network may cause system crashes, privilege elevation, or arbitrary code execution Description: A heap buffer overflow exists in the AirPort wireless driver's handling of scan cache updates. An attacker in local proximity may be able to trigger the overflow by injecting a maliciously-crafted frame into the wireless network. This could lead to a system crash, privilege elevation, or arbitrary code execution with system privileges. This issue affects Intel-based Mac mini, MacBook, and MacBook Pro computers equipped with wireless. Power Mac, PowerBook, iBook, iMac, Mac Pro, Xserve, and PowerPC-based Mac mini computers are not affected. This update addresses the issue by performing additional validation of wireless frames. There is no known exploit for this issue. This issue does not affect systems prior to Mac OS X v10.4.

AirPort CVE-ID: CVE-2006-3509 Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7 Impact: Depending upon third-party wireless software in use, attackers on the wireless network may cause crashes or arbitrary code execution Description: An integer overflow exists in the Airport wireless driver's API for third-party wireless software. This could lead to a buffer overflow in such applications dependent upon API usage. No applications are known to be affected at this time. If an application is affected, then an attacker in local proximity may be able to trigger an overflow by injecting a maliciously-crafted frame into the wireless network. This may cause crashes or lead to arbitrary code execution with the privileges of the user running the application. This issue affects Intel-based Mac mini, MacBook, and MacBook Pro computers equipped with wireless. Power Mac, PowerBook, iBook, iMac, Mac Pro, Xserve, and PowerPC-based Mac mini computers are not affected. This update addresses the issues by performing additional validation of wireless frames. There is no known exploit for this issue. This issue does not affect systems prior to Mac OS X v10.4.
