Impact

A remote attacker could execute arbitrary code, cause a Denial of Service condition, bypass intended memory-read restrictions, conduct a timing side-channel attack to bypass the Same Origin Policy, obtain sensitive information, or spoof the address bar.

Workaround

There is no known workaround at this time.

Resolution

All WebKitGTK+ users should upgrade to the latest version:
