Opera Fixes Browser Takeover Flaws
Page 1 of 1
Norway-based Opera Software has rushed out a new versions of its alternative Web browser products to plug "highly critical" security flaws that could lead to system takeover.
The security vulnerabilities, which affect both Linux and Windows systems, were detected in the way the Opera browser handles skin files. It is the third time this year that Opera has issued major updates to fix security issues.
The Opera updates include a fix for a boundary error in the .ZIP processing feature when skin files are being handled. A successful exploit -- which involved tricking a user into visiting a specially-crafted Website -- could cause a buffer overflow and lead to arbitrary code execution, said Finnish researcher Jouko Pynnonen.
Both vulnerabilities affect version 7.22 and prior, Opera confirmed. The company is urging all users to upgrade to version 7.23.
The serious Opera flaws come at a crucial time for the company, which competes directly with Microsoft's Internet Explorer and the Mozilla Foundation's Phoenix browser.
The company has made inroads in the mobile sector, rolling out a new platform designed to fully integrate browser technology with applications on handheld devices. It has also scored deals to put a stripped down browser on mobile devices made by Nokia, Sony Ericsson, Sendo and BenQ.
