As much as I love Opera, it is still just software, and that means it too is vulnerable to security issues. Maybe not as badly as IE or Firefox, but vulnerable nonetheless. That said, I’d be remiss if I only posted about Opera’s positives and ignored this bit of news:
It is being reported that Opera v9.20 is vulnerable to an attack which causes it to consume 100% of its host machine’s resources, rendering the PC unusable.
There is currently no work-around so anyone worried about this situation should disable the BitTorrent engine within Opera by following the instructions found on Opera’s site.
Fortunately I wouldn’t have been affected by this. The first thing I did after installing Opera 9.2 was disable BitTorrent downloading in the browser, as I much prefer µTorrent.
