Opera 11.01 is a recommended upgrade offering security and stability
enhancements.

The following security vulnerabilities have been fixed :

- Removed support for 'javascript:' URLs in CSS -o-link values, to
make it easier for sites to filter untrusted CSS.

- Fixed an issue where large form inputs could allow execution of
arbitrary code, as reported by Jordi Chancel; see our advisory.

- Fixed an issue which made it possible to carry out clickjacking
attacks against internal opera: URLs; see our advisory.

- Fixed issues which allowed web pages to gain limited access to files
on the user's computer; see our advisory.

- Fixed an issue where email passwords were not immediately deleted
when deleting private data; see our advisory."

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)"
