Opera JavaScript invalid pointer reference code execution
| opera-javascript-code-execution (36039) |  High Risk |
Description:
Opera could allow a remote attacker to execute arbitrary code on the system, caused by an error when handling certain specially-crafted JavaScript. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using a virtual function call on an invalid pointer to reference malformed data and execute arbitrary code on the vulnerable system.
