CVE-2015-3738

Vulnerability

A memory corruption vulnerability exists in WebKit, the rendering engine used in Apple iOS (prior to 8.4.1) and Safari (prior to 6.2.8, 7.1.8, and 8.0.8). The flaw is triggered when processing a maliciously crafted website, leading to a memory corruption issue that can cause unexpected application termination or arbitrary code execution [1][2].

Exploitation

An attacker can exploit this vulnerability by enticing a user to visit a specially crafted website. No authentication or special network position is required beyond standard web access. The attack requires user interaction (visiting the site) but no additional privileges. The exact mechanism of the memory corruption is not publicly detailed, but the code path is reachable through normal WebKit content parsing.

Impact

Successful exploitation allows a remote attacker to execute arbitrary code on the target system, potentially leading to full compromise of the affected device. The impact includes denial of service (application crash) and arbitrary code execution with the privileges of the WebKit process [1][2].

Mitigation

Apple released security updates to address this vulnerability: iOS 8.4.1 for iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later; and Safari 8.0.8, Safari 7.1.8, and Safari 6.2.8 for OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.5, and OS X Yosemite v10.10.4 [1][2]. Users should update their software to the latest versions as soon as possible.
