Opera JPEG DHT marker buffer overflow
| opera-jpeg-dht-bo (31305) |  High Risk |
Description:
Opera is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the JPEG DHT marker. By creating a Web site containing a specially-crafted DHT marker, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the victim, if the attacker could persuade the victim to visit the malicious Web site.
