TITLE

Apple Mac OS X of CoreAudio Vulnerable to arbitrary code execution

DESCRIPTION

CoreAudio in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted audio content with QDM2 encoding, which triggers a buffer overflow due to inconsistent length fields, related to QDCA. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. 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 during the rendering of an audio stream utilizing QDesign's audio codec. The application will perform an allocation utilizing a field specified in the sample's description. Later when initializing the buffer, the application will utilize a different length. If the lengths differ, then a buffer overflow will occur. This can lead to code execution under the context of the currently logged in user. Apple QuickTime is prone to a memory-corruption vulnerability when parsing QDM2 and QDCA encoded audio data. Failed exploit attempts will likely result in a denial-of-service condition. NOTE: This issue was previously covered in BID 39020 (Apple Mac OS X APPLE-SA-2010-03-29-1 Multiple Security Vulnerabilities) but has been assigned its own record to better document it. Mac OS X is the operating system used by the Apple family of machines. A buffer overflow vulnerability exists in CoreAudio versions of Apple Mac OS prior to 10.6.3. -- Vendor Response: Apple has issued an update to correct this vulnerability.
