These details were obtained through the Packet Storm Bug Bounty program and are being released to the community.   +------------------------------------------------------------------------------+   +---------+ | DETAILS | +---------+   The 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.   The exploit for this vulnerability is a 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).   +------------------------------------------------------------------------------+   +------------------+ | PROOF OF CONCEPT | +------------------+   The full exploit code is available here: http://packetstormsecurity.com/files/123088/ https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/28081.tgz   +------------------------------------------------------------------------------+   +---------------+ | RELATED LINKS | +---------------+   http://lists.apple.com/archives/security-announce/2012/Nov/msg00001.html http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-3748   +------------------------------------------------------------------------------+     +----------------+ | SHAMELESS PLUG | +----------------+   The Packet Storm Bug Bounty program gives researchers the ability to profit from their discoveries.You can get paid thousands of dollars for one day and zero day exploits.Get involved by contacting us at getpaid@packetstormsecurity.com or visit the bug bounty page at:   http://packetstormsecurity.com/bugbounty/     -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux)   iEYEARECAAYFAlImrisACgkQrM7A8W0gTbHnIwCfR6vCe/+YjbxYoeHaErbHYDsN bC0An34R0Am9RemKiIDnoa+hD3pT+M0y =VXyD -----END PGP SIGNATURE-----
