The Opera Web Browser fails to properly process overly long URLs. This vulnerability may allow arbitrary code execution.
Opera is a multi-platform web browser that is available for a range of operating systems and embedded Internet products. Opera contains a heap buffer overflow vulnerability in the way that it parses tags containing long URLs. This vulnerability could be exploited by a remote attacker with the ability to construct a web page containing a specially crafted malicious tag and the ability to coerce an Opera user into visiting the page.
A remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user running the vulnerable version of Opera or cause the browser to crash, resulting in a denial of service condition.
Update
Opera has released an update to address this issue. See Opera Advisory 848 for more details.
