CVE-2012-0592

TITLE

plural Apple Used in products WebKit Vulnerable to arbitrary code execution

DESCRIPTION

WebKit, as used in Apple iOS before 5.1 and iTunes before 10.6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2012-03-07-1 and APPLE-SA-2012-03-07-2. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The flaw exists within the JavaScriptCore component as used by WebKit. This module is responsible for the in browser implementation of JavaScript. When handling the array.splice method the browser improperly calculates the length, and thus allocation size for the newly modified array. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the browser. Failed exploit attempts will crash the application. NOTE: This issue was previously discussed in BID 52365 (WebKit Multiple Unspecified Memory Corruption Vulnerabilities) but has been given its own record to better document it. WebKit is a set of open source web browser engines jointly developed by companies such as KDE, Apple (Apple), and Google (Google), and is currently used by browsers such as Apple Safari and Google Chrome. WebKit is vulnerable when used in Apple iOS versions prior to 5.1 and iTunes prior to 10.6. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

For more information see vulnerability #21 in: SA47843 5) A race condition error in the Passcode Lock component when handling slide to dial gestures can be exploited to bypass the Passcode Lock screen. 6) The weakness is caused due to the Private Browsing mode in Safari not properly preventing recording of visits to certain sites using the pushState or replaceState JavaScript methods. 7) An error within the Siri component when handling voice commands can be exploited to bypass the screen lock and forward an open mail message to an arbitrary recipient. 8) A format string error in the VPN component when handling racoon configuration files can be exploited to execute arbitrary code via a specially crafted racoon configuration file. 10) An error within the WebKit component when handling drag-and-drop actions can be exploited to conduct cross-site scripting attacks. 11) Multiple unspecified errors within the WebKit component can be exploited to conduct cross-site scripting attacks. 12) Some vulnerabilities are caused due to a bundled vulnerable version of WebKit. SOLUTION: Apply iOS 5.1 Software Update.
