Description

Jakob Balle of Secunia reported two vulnerabilities in windows with multiple tabs. Malicious content in a background tab can attempt to steal information intended for the topmost tab by popping up prompt dialog that appears to come from the trusted site, or by silently redirecting input focus to a background tab hoping to catch the user inputting something sensitive.

Jesse Ruderman and Martin Wargers discovered variants

Workaround

Do not open sites with sensitive content in the same window as tabs from untrusted content. Upgrade to fixed version.
