Serious security holes fixed in Opera – but Mac App Store users left at risk again

Opera has released a new version of its web browser – version 12.13 – and recommended that users update their installations to benefit from a series of security fixes as well as the usual “stability enhancements”.

Version 12.13 of Opera for Windows, Mac and Linux is available for download from the Opera website, and you can read about the fixed security issues (including a high severity vulnerability that could be exploited to cause the web browser to crash, and in some cases execute arbitrary code such as malware, and another about how Opera handles boobytrapped SVG files) in their changelog.

It should go without saying that if you use Opera, you should update to version 12.13 as soon as possible.
