TITLE

Apple Mac OS X of PDFKit Vulnerable to arbitrary code execution

DESCRIPTION

Use-after-free vulnerability in PDFKit in Apple Mac OS X before 10.8.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted ink annotations in a PDF document. 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 exists within the parsing of a PDF file. During the processing of a specific InkList array, a reference is created to an object that is freed before use. By abusing this behavior an attacker can ensure this memory is under control and leverage the situation to achieve remote code execution under the context of the user currently logged in. Apple Mac OS X is prone to multiple vulnerabilities. The update addresses new vulnerabilities that affect Apache, CoreTypes, IOAcceleratorFamily, Login Window, Messages, PDFKit, and Software Update. Attackers can exploit these issues to execute arbitrary code, cause denial-of-service conditions, gain unauthorized access, obtain sensitive information, bypass security restrictions, and perform other attacks. These issues affect OS X prior to 10.8.3. Note: This issue was previously discussed in BID 58494 (Apple Mac OS X Security Update 2013-001 Multiple Security Vulnerabilities), but has been given its own record to better document it. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2013-03-14-1 OS X Mountain Lion v10.8.3 and Security Update 2013-001 OS X Mountain Lion v10.8.3 and Security Update 2013-001 is now available and addresses the following: Apache Available for: Mac OS X 10.6.8, Mac OS X Server 10.6.8, OS X Lion v10.7 to v10.7.5, OS X Lion Server v10.7 to v10.7.5, OS X Mountain Lion v10.8 to v10.8.2 Impact: An attacker may be able to access directories that are protected with HTTP authentication without knowing the correct credentials Description: A canonicalization issue existed in the handling of URIs with ignorable Unicode character sequences. This issue was addressed by updating mod_hfs_apple to forbid access to URIs with ignorable Unicode character sequences.
