Description:
Several vulnerabilities were reported in Opera. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can conduct cross-site scripting attacks.
A remote user can create a specially crafted URL that, when loaded by the target user, will trigger a memory allocation error and execute arbitrary code on the target system. The code will run with the privileges of the target user.
Andrey Stroganov reported this vulnerability.
A remote user can generate a small window that obscures a download dialog, potentially causing the target user to run a downloaded executable.
Jordi Chancel reported this vulnerability.
The software may not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser and run in the security context of an arbitrary site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
An unspecified "low severity issue" was reported. The impact was not specified.
