Opera < 11.01 Multiple Vulnerabilities

High Nessus Plugin ID 51774


The remote host contains a web browser that is affected by multiple vulnerabilities


The version of Opera installed on the remote Windows host is earlier than 11.01. Such versions are potentially affected by the following issues :

- The Cascading Style Sheets (CSS) Extensions for XML implementation recognizes links to javascript: URLs in the -o-link property, which could be abused to bypass CSS filtering. (CVE-2011-0681)

- An integer truncation error exists such that the application may crash when accessing web pages that contain forms having large numbers of items in an 'option' element. Such crashes may lead to memory corruption and allow code execution. (982)

- An error exists in the handling of internal 'opera:' URLS that can allow anti-clickjacking configuration options to be modified. (983)

- An error exists in the processing of certain HTTP requests and responses that can allow limited, unauthorized access to local files. (984)

- An error exists in the downloads manager that allows unintended executables to be used when attempting to open the folder containing a downloaded file. (985)

- An error exists in the private data deletion process that causes the removal of email passwords to be delayed. (986)


Upgrade to Opera 11.01 or later.
