**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 40.0.2214.91 Opera (affected versions not specified) **Description** The issue concerns the FileSystem API in Google Chrome and Opera, which can be exploited by a remote attacker to bypass the SafeBrowsing protection mechanism for executable files.

For Opera, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
