Multiple vulnerabilities have been discovered in Opera. Please review the CVE identifiers referenced below for details.
A remote attacker could entice a user to open a specially crafted web page, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. A remote attacker may be able to: trick users into downloading and executing arbitrary files, bypass intended access restrictions, spoof trusted content, spoof URLs, bypass the Same Origin Policy, obtain sensitive information, force subscriptions to arbitrary feeds, bypass the popup blocker, bypass CSS filtering, conduct cross-site scripting attacks, or have other unknown impact.
A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application or possibly obtain sensitive information.
A physically proximate attacker may be able to access an email account.
There is no known workaround at this time.
All Opera users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-12.00.1467"
