Opera fixes critical form-handling flaw

Second act, malicious spies and click-jackers exit stage left

Beginner's guide to SSL certificates

Opera has updated its browser to correct a cross-platform vulnerability that created a possible mechanism for hackers to inject malicious code into vulnerable systems.

The critical security bug stemmed from flaws in handling large form inputs, as explained in an advisory by the Norwegian software developer here. Version 11.01 of the browser also addresses two less serious security bugs. The first involves a click-jacking vulnerability and the second involves a privacy flaw that creates a way for operators of malicious sites to spy on a surfer's private files. More discussion on the flaws can be found in a bulletin from Secunia here.

The browser update – for Mac and Unix as well as Windows machines, and released on Wednesday – also includes a number of lesser performance tweaks.

In other patching news this week, VideoLAN project developers have released a new version of VLC Media Player that fixes flaws involving the handling of Real Media and CDG media files. Exploitation would involve tricking a user into opening a maliciously constructed file. More details on the update to the popular open source media player application can be found in an advisory by Secunia here. ®
