Opera < 11.64 URL Parsing Memory Corruption

Critical Nessus Plugin ID 59089


The remote host contains a web browser that is potentially affected by a memory corruption vulnerability.


The version of Opera installed on the remote Windows host is earlier than 11.64 and is, therefore, potentially affected by a memory corruption vulnerability.

Certain crafted URLs can cause the application to allocate incorrect amounts of memory and overwrite unrelated memory. This corruption can then lead to application crashes or even arbitrary code execution.


Upgrade to Opera 11.64 or later.
