TITLE

Apple Mac OS X of Apple Type Services Heap-based buffer overflow vulnerability

DESCRIPTION

Heap-based buffer overflow in Apple Type Services (ATS) in Apple Mac OS X before 10.6.7 allows remote attackers to execute arbitrary code via a document that contains a crafted embedded OpenType font. Apple Mac OS X is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. Versions prior to OS X 10.6.7 are vulnerable. NOTE: This issue was previously discussed in BID 46950 (Apple Mac OS X Prior to 10.6.7 Multiple Security Vulnerabilities) but has been given its own record to better document it. Apple Mac OS X is a dedicated operating system developed by Apple for Mac computers. ---------------------------------------------------------------------- Meet Secunia @ Microsoft Management Summit (MMS) in Las Vegas, USA (21-25 March). http://secunia.com/company/events/mms_2011/ ---------------------------------------------------------------------- TITLE: Apple Mac OS X Multiple Vulnerabilities SECUNIA ADVISORY ID: SA43814 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/43814/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=43814 RELEASE DATE: 2011-03-22 DISCUSS ADVISORY: http://secunia.com/advisories/43814/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/43814/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=43814 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: Apple has issued a security update for Mac OS X, which fixes multiple vulnerabilities. 1) A divide-by-zero error in AirPort when handling Wi-Fi frames can be exploited to cause a system reset. 2) Multiple vulnerabilities in Apache can be exploited by malicious people to disclose potentially sensitive information and by malicious users and malicious people to cause a DoS (Denial of Service). For more information: SA40206 3) A format string error within AppleScript Studio when handling certain commands via dialogs can be exploited to potentially execute arbitrary code. For more information: SA41452 9) An error within the "FSFindFolder()" API in CarbonCore when used with the "kTemporaryFolderType" flag can be exploited to disclose the contents of arbitrary directories. 10) Multiple errors in ClamAV can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system. For more information: SA41503 SA42426 11) An unspecified error in the handling of embedded fonts in CoreText can be exploited to corrupt memory when a specially crafted document is viewed or downloaded. 12) An integer overflow error within the handling of the F_READBOOTSTRAP ioctl in HFS, HFS+, and HFS+J filesystems can be exploited to read arbitrary files. 13) An error in ImageIO within the handling of JPEG files can be exploited to cause a heap-based buffer overflow. 15) An error in libTIFF within the handling of JPEG encoded TIFF files can be exploited to cause a buffer overflow. 16) An error in libTIFF within the handling of CCITT Group 4 encoded TIFF files can be exploited to cause a buffer overflow. 17) An integer overflow error in ImageIO within the handling of JPEG encoded TIFF files can be exploited to potentially execute arbitrary code. 18) Multiple errors in Image RAW when handling Canon RAW image files can be exploited to cause buffer overflows. 19) An error in the Install Helper when handling URLs can be exploited to install an arbitrary agent by tricking the user into visiting a malicious website. 20) Multiple errors in Kerberos can be exploited by malicious users and malicious people to conduct spoofing attacks and bypass certain security features. 22) An integer truncation error within Libinfo when handling NFS RPC packets can be exploited to cause NFS RPC services to become unresponsive. 23) An error exists in the libxml library when traversing the XPath. For more information: SA42175 24) A double free error exists in the libxml library when handling XPath expressions. For more information: SA42721 25) Two errors in Mailman can be exploited by malicious users to conduct script insertion attacks. For more information: SA41265 26) Multiple errors in PHP can be exploited by malicious users and malicious people to bypass certain security restrictions and by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system. For more information: SA39573 SA41724 27) Multiple errors in PHP can be exploited by malicious users and malicious people to bypass certain security restrictions. For more information: SA41724 28) An error in the OfficeImport framework when processing records containing formulas shared between multiple cells can be exploited to corrupt memory and potentially execute arbitrary code. 29) An error in QuickLook when handling certain Microsoft Office files can be exploited to corrupt memory when a specially crafted document is downloaded. 30) Multiple unspecified errors in QuickTime when handling JPEG2000, FlashPix, and panorama atoms in QTVR (QuickTime Virtual Reality) movie files can be exploited to corrupt memory via specially crafted files. 31) An integer overflow error in QuickTime when handling certain movie files can be exploited to potentially execute arbitrary code when a specially crafted file is viewed. 32) An error within QuickTime plug-in when handling cross-site redirects can be exploited to disclose video data. This vulnerability only affects 64-bit Ruby processes. 34) A boundary error in Samba can be exploited by malicious people to potentially compromise a vulnerable system. For more information: SA41354 35) A security issue in Subversion can be exploited by malicious people to bypass certain security restrictions. For more information: SA41652 36) A weakness in Terminal uses SSH version 1 as the default protocol version when using ssh via the "New Remote Connection" dialog. 37) Some vulnerabilities in FreeType can be exploited to cause a DoS (Denial of Service) or potentially compromise an application using the library. For more information: SA41738 SOLUTION: Update to version 10.6.7 or apply Security Update 2011-001. PROVIDED AND/OR DISCOVERED BY: 15, 16, 33) Reported by the vendor.
