Files could be overwritten on the remote host.
The version of Opera installed on the remote host contains a file
corruption vulnerability. This issue is exposed when a user is
presented with a file dialog, which will cause the creation of a
temporary file. It is possible to specify a relative path to another
file on the system using directory traversal sequences when the
download dialog is displayed. If the client user has write
permissions to the attacker-specified file, it will be corrupted.
This could be exploited to delete sensitive files on the systems.
Install Opera 7.23 or newer.
