execute arbitrary commands.

<vulnerable range="lt">8.51</vulnerable>
Opera is a multi-platform web browser.
Peter Zelezny discovered that the shell script used to launch
Opera parses shell commands that are enclosed within backticks in the
URL provided via the command line.
<impact type="normal">
A remote attacker could exploit this vulnerability by enticing a
user to follow a specially crafted URL from a tool that uses Opera to
open URLs, resulting in the execution of arbitrary commands on the
targeted machine.
There is no known workaround at this time.
All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/opera-8.51&quot;</code>
