Opera has shipped a high-priority update to its flagship Web browser to correct <A HREF="http://www.eweek.com/c/a/Security/Serious-Browser-Bugs-Spoil-Opera-Tune/?kc=EWKNLEDP022108C">multiple flaws that put Windows users at risk</A> of malicious hacker attacks.

With Opera 9.26 for Windows, the Norwegian company shipped patches for at least three vulnerabilities that can be exploited to launch malware installations or conduct identity theft attacks.

The most serious of the three bugs--rated "highly severe" by Opera--can cause the browser to be tricked into treating custom comments in image properties as script.
