Description

Multiple vulnerabilities have been discovered in Opera. Please review
the CVE identifiers referenced below for details.


Impact

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.

Workaround

There is no known workaround at this time.
