Summary

The remote host is using Opera - an alternative web browser. This version is vulnerable to an issue when handling large JavaScript arrays. In particular, it is possible to crash the browser when performing various operations on Array objects with 99999999999999999999999 or 0x23000000 elements. The crash is due to a segmentation fault and may be indicative of an exploitable memory corruption vulnerability, possibly resulting in arbitrary code execution.
