Opera 12.12发布

On 2012年12月18日, in soft, by netoearth

Opera users take note, a new version of your beloved browser has been released bringing the stable release channel version of the Internet browser to 12.12. Opera 12.12 is a recommended stability and security update for the browser that all Opera 12.11 and earlier users should install as soon as possible to protect their browser from exploits targeting the security vulnerabilities.

You are probably wondering what’s new in Opera 12.12. Here is a quick rundown of the changes found in the release:

The Delete Private Data dialog (under Opera > Settings > Delete Private Data) has a new setting. Delete settings and data for all extensions is turned off by default and you need to check it to include it in the deletion process.

When you check the feature you are telling Opera to delete all data that extensions have generated since their installation. While I can’t verify it 100%, it also appears as if all settings of all extensions are reset to their default values by this operation so use this with caution as you may delete all of your custom configurations this way. Please note that this will include disabled extensions and not only extensions that are enabled in the browser.

Two additional fixes affect the Delete Private Data dialog. The first fixed a serious issue where the feature could delete extensions and settings data which for obvious reasons should not have happened as earlier versions of Opera did not include that feature. The second is a redesign of the Delete Private Data dialog window so that it is better usable on smaller screens.

The developers in addition have made several general stability improvements and fixes in the new version that they do not mention individually.

As far as security goes, the following vulnerabilities have been fixed in Opera 12.12:

  • Fixed an issue where malformed GIF images could allow execution of arbitrary code
  • Fixed an issue where private data could be disclosed to other computer users, or be modified by them
  • Fixed an issue where repeated attempts to access a target site could trigger address field spoofing

Opera 12.12 is already available for download at the official Opera website. You can check for updates from within the browser with a click on Opera > Help > Check for updates.
