-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-077 : Apple QuickTime QTVR QTVRStringAtom Parsing Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-077 June 6, 2012 - -- CVE ID: CVE-2012-0667 - -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P - -- Affected Vendors: Apple - -- Affected Products: Apple QuickTime - -- Vulnerability Details: 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 within the QuickTimeVR.qtx component. A signedness error exists when processing a QTVRStringAtom having an overly large "stringLength" parameter. This can be exploited to cause a stack-based buffer overflow and execute arbitrary code under the context of the user running the application. - -- Vendor Response: Apple has issued an update to correct this vulnerability.
