Opera, the Norwegian software company, rushed to release a patch for the latest major release its multi-platform Web browser on Wednesday, following five security advisories that were released on Tuesday, three of them rated critical.
The advisories, from Israeli company GreyMagic Software, were issued just a week after Opera released version 7.0 of its eponymous browser, reviewed here. On Wednesday, those who had downloaded Opera 7.0 were being urged to upgrade to version 7.01, which fixed the bugs. The upgrade is available on Opera's Web site.
The third critical exploit uses a flaw in the browser's graphics-handling routines to achieve the same results.
GreyMagic said Opera "lived up to its excellent response record and released version 7.01 only 5 days after initial notification."
An Opera spokeswoman said there was "a question of communication -- we did try to address it and we would have liked to have addressed it fully at the time, but we have done it now."
She said Opera has no figures on how many people have downloaded Opera 7.0, but Download.com reports three million downloads of Opera 7.0 since the application was first posted on 28 January, 2003. (Download.com is owned by ZDNet UK parent company CNET Networks.) The spokeswoman said Opera had not heard of any users experiencing problems as a result of the flaws.
Opera is available free of charge with a sponsored advertising banner in the top-right corner of the user interface. To remove the advertising banner users must register their version for $39 (about £24).
