Karol Wiesek and Greg MacManus reported via iDEFENSE that the Opera web browser contains a flaw in the handling of certain URIs. When presented with these URIs, Opera would invoke external commands to process them after some validation. However, if the hostname component of a URI begins with a `-', it may be treated as an option by an external command. This could have undesirable side-effects, from denial-of-service to code execution. The impact is very dependent on local configuration.

After the iDEFENSE advisory was published, the KDE team discovered similar problems in KDE's URI handlers.
