Opera Update Fixes URL Buffer Overflow Vulnerability

Posted on May 15th, 2012 by

Opera has released version 11.64 of the company’s web browser, and this update is essentially a security release for an issue where certain URL constructs can allow arbitrary code execution. Opera’s security advisory says:

Certain page address (URL) constructs can cause Opera to allocate the wrong amount of memory for storing the address. When it then attempts to store the address, it will overwrite unrelated memory with attacker-controlled data. This can lead to a crash, which may also execute that data as code.

Users can update Opera using the browser’s built-in auto-updater or can download a new version from the Opera web site.
