List of CVEs: CVE-2015-1155

Versions of Safari before 8.0.6, 7.1.6, and 6.2.6 are vulnerable to a "state management issue" that allows a browser window to be navigated to a file:// URL. By dropping and loading a malicious .webarchive file, an attacker can read arbitrary files, inject cross-domain Javascript, and silently install Safari extensions.
