Apple Mac OS X Pre 10.4.8 Multiple Security Vulnerabilities

Risk

High

Date Discovered

September 29, 2006

Description

Apple Mac OS X is prone to multiple security vulnerabilities. These issue affect Mac OS X and various applications including CFNetwork, Safari, Kernel, ImageIO, LoginWindow, System Preferences, QuickDraw Manager, and Workgroup Manager. An attacker can exploit these issues to execute arbitrary code, gain elevated privileges, cause denial-of-service conditions, and gain unauthorized access. Apple Mac OS X versions prior to 10.4.8 are vulnerable to these issues.

Recommendations

Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.

Given the local nature of some of these issues, grant only trusted individuals access to the affected system.

Run all software as a nonprivileged user with minimal access rights.

Run all applications with the minimal amount of privileges required for functionality. This can reduce the impact of latent vulnerabilities.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploitation attempts or activity that results from successful exploitation.

Do not accept or execute files from untrusted or unknown sources.

Users should avoid downloading and opening files that originate from unknown or questionable sources.

Do not follow links provided by unknown or untrusted sources.

Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.

Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as non-executable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploitation of memory-corruption vulnerabilities.
The vendor has released Mac OS X 10.4.8 to address these issues. Please see the referenced advisories for more information.
