TITLE

Apple Mac OS X of Apple Type Services (ATS) Vulnerable to arbitrary code execution

DESCRIPTION

Heap-based buffer overflow in Apple Type Services (ATS) in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows remote attackers to execute arbitrary code via a crafted Compact Font Format (CFF) font. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw appears to exist in the ATSServer font server upon parsing of malicious Compact Font Format files. A boundary condition exists in the parsing of internal dictionaries that can lead to a memory corruption allowing the execution of arbitrary code. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2009-002. The security update addresses new vulnerabilities that affect Apple Type Services, CFNetwork, CoreGraphics, Disk Images, Help Viewer, iChat, ICU, Kernel, Launch Services, QuickDraw Manager, and Spotlight components of Mac OS X. The advisory also contains security updates for 47 previously reported issues. An attacker can exploit this issue to execute arbitrary code in the context of the application using the component. Failed exploit attempts will cause a denial-of-service condition. I. II. Impact The impacts of these vulnerabilities vary. Potential consequences include arbitrary code execution, sensitive information disclosure, denial of service, or privilege escalation. III. These and other updates are available via Software Update or via Apple Downloads. IV.

Researchers interested in getting paid for their security research through the ZDI can find more information and sign-up at: http://www.zerodayinitiative.com The ZDI is unique in how the acquired vulnerability information is used. TippingPoint does not re-sell the vulnerability details or any exploit code. Instead, upon notifying the affected product vendor, TippingPoint provides its customers with zero day protection through its intrusion prevention technology. Explicit details regarding the specifics of the vulnerability are not exposed to any parties until an official vendor patch is publicly available. Furthermore, with the altruistic aim of helping to secure a broader user base, TippingPoint provides this vulnerability information confidentially to security vendors (including competitors) who have a vulnerability protection or mitigation product.
