Opera posts security update for Apple and Windows

Opera Software has released an update for its web browser.

The company said that the 10.53 update would address security vulnerabilities in both the Mac and Windows version of the browser.

Opera said that the update would address a vulnerability which the company classifies as "extremely severe."

The company said that the vulnerability lies within a script that handles document files.

An attacker could potentially modify a file to make multiple calls to the vulnerable component and cause an application crash.

From there, a targeted system would be vulnerable to remote code execution.

Users of both the MacOS X and Windows versions of the browser are being advised to install the update. Other versions of Operawere not listed as vulnerable to attack.

The update comes as Opera is seeking to expand the reach of its browser business. The company has in recent weeks released an iPhone version of the browser and in March an updated version of Opera for the Android smartphone platform was debuted.
