Opera posts security update for Apple and Windows

The Opera flaw leaves systems vulnerable to remote code execution

Opera Software has released a 10.53 update that addresses "extremely severe" security vulnerabilities in the Mac and Windows version of the browser.

The company said that the vulnerability lies within a script that handles document files. An attacker could 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 the Mac OS X and Windows versions of the browser are being advised to install the update. Other versions of Operawere not listed as vulnerable.

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