TITLE

Apple Mac OS X of CoreGraphics Integer overflow vulnerability

DESCRIPTION

Integer overflow in CoreGraphics in Apple Mac OS X 10.4.11, 10.5.2, and 10.5.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a PDF file with a long Type 1 font, which triggers a heap-based buffer overflow. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2008-005. The security update addresses a total of six new vulnerabilities that affect the CarbonCore, CoreGraphics, Data Detectors Engine, Disk Utility, OpenLDAP, and QuickLook components of Mac OS X. The advisory also contains security updates for 11 previously reported issues. NOTE: This BID is being retired; the following individual records have been created to better document these issues: 30487 Apple Mac OS X CarbonCore Stack Based Buffer Overflow 30488 Apple Mac OS X CoreGraphics Multiple Memory Corruption Vulnerabilities 30489 Apple Mac OS X CoreGraphics Heap Based Buffer Overflow Vulnerability 30490 Apple Mac OS X Data Detectors Engine Denial Of Service Vulnerability 30492 Apple Mac OS X Disk Utility Privilege Escalation Vulnerability 30493 Apple Mac OS X QuickLook Multiple Memory Corruption Vulnerabilities. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed attempts will likely cause denial-of-service conditions. 1) A vulnerability in BIND can be exploited to poison the DNS cache. For more information: SA30973 2) A boundary error exists in CarbonCore when handling filenames. This can be exploited to cause a stack-based buffer overflow via overly long filenames. 3) Multiple errors exist in CoreGraphics when processing received arguments. These can be exploited to trigger a memory corruption by e.g. tricking a user into visiting a specially crafted website. This can be exploited to cause a heap-based buffer overflow via a specially crafted PDF file. 5) Multiple errors in QuickLook when downloading Microsoft Office files can be exploited to cause a memory corruption. 6) An error exists in the Data Detectors engine when viewing a specially crafted message. This can be exploited to consume overly large resources and trigger an application using the engine to terminate. 7) The problem is that the "Repair Permissions" tool included in Disk Utility sets the "setuid" bit on "/usr/bin/emacs". This can be exploited to execute arbitrary commands with system privileges. 8) An error in OpenLDAP when parsing ASN.1 BER encoded packets can be exploited to cause a DoS. For more information: SA30853 9) A boundary error exists in the OpenSSL "SSL_get_shared_ciphers()" function. For more information see vulnerability #4 in: SA22130 10) Some vulnerabilities in PHP can be exploited malicious users to bypass certain security restrictions, and potentially by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system. For more information: SA30048 11) Two vulnerabilities in rsync can be exploited by malicious users to bypass certain security restrictions.

For more information, see the vendor's site found at the following link URL. http://www.apple.com/macosx/ II. This vulnerability exists due to the way PDF files containing Type 1 fonts are handled. When processing a font with an overly large length, integer overflow could occur. III. An attacker could exploit this issue via multiple attack vectors. The most appealing vector for attack is Safari. An attacker could host a malformed PDF file on a website and entice a targeted user to open a URL. Upon opening the URL in Safari the PDF file will be automatically parsed and exploitation will occur. While this is the most appealing attack vector, the file can also be attached to an e-mail. Any application which uses the Apple libraries for file open dialogs will crash upon previewing the malformed PDF document. IV. Previous versions may also be affected. V. WORKAROUND iDefense is currently unaware of any workarounds for this issue. VI. More information is available at the following URL. http://support.apple.com/kb/HT2647 VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2008-2322 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
