Packet Storm Exploit 2013-0903-1 - Apple Safari Heap Buffer Overflow: Posted Sep 4, 2013; Authored by Vitaliy Toropov | Site packetstormsecurity.com; A heap memory buffer overflow vulnerability exists within the WebKit's JavaScriptCore JSArray::sort(...) method. The exploit for this vulnerability is javascript code which shows how to use it for memory corruption of internal JS objects (Unit32Array and etc.) and subsequent arbitrary code execution (custom ARM/x64 payloads can be pasted into the JS code). This exploit affects Apple Safari version 6.0.1 for iOS 6.0 and OS X 10.7/8. Earlier versions may also be affected. It was obtained through the Packet Storm Bug Bounty program.; tags | exploit, overflow, arbitrary, javascript, code execution, bug bounty, packet storm; systems | apple, osx, iphone, ios; advisories | CVE-2012-3748; SHA-256 | 14c94c8c5cb510aa3236b42b9618aa54726915b4e116afea229961e936fb158d; Download | Favorite | View

Packet Storm Advisory 2013-0903-1 - Apple Safari Heap Buffer Overflow: Posted Sep 4, 2013; Authored by Vitaliy Toropov | Site packetstormsecurity.com; A heap memory buffer overflow vulnerability exists within the WebKit's JavaScriptCore JSArray::sort(...) method. This method accepts the user-defined JavaScript function and calls it from the native code to compare array items. If this compare function reduces array length, then the trailing array items will be written outside the "m_storage->m_vector[]" buffer, which leads to the heap memory corruption. This finding was purchased through the Packet Storm Bug Bounty program.; tags | advisory, overflow, arbitrary, javascript, code execution, bug bounty, packet storm; systems | apple, osx, iphone, ios; advisories | CVE-2012-3748; SHA-256 | 84bd76ba4dce1e485a3431a2c7bbd07c262e86f184ca05e0931fac224f9ab746; Download | Favorite | View
