Synopsis
=======
Lack of URL validation in Opera command-line wrapper could be abused to
execute arbitrary commands.
Background
=========
Opera is a multi-platform web browser.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/opera < 8.51 >= 8.51
Description
==========
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
=====
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.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-8.51"
