Windows 7: Opera says bug probably can't commandeer machines.

Get your DEP here just in case.

A security vulnerability identified in Opera can be exploited to crash users' browsers, but probably can't lead to the remote execution of malware, a company spokesman said.
The buffer overflow bug was disclosed by Vupen Security on Thursday, and the report has since been picked up by others, including Secunia and Sans. The advisories have said the vulnerability is critical because it can be exploited to remotely execute malicious code on end user machines.

Vupen officials didn't respond to emails seeking details. But Opera isn't so sure.
