Trillian UTF-8 buffer overflow
| trillian-utf8-bo (34918) |  High Risk |
Description:
Trillian is vulnerable to a heap-based buffer overflow, caused by improper validation of UTF-8 messages when the MSN protocol is used. By persuading the victim to view a specially-crafted UTF-8-encoded message, a remote attacker could overflow a buffer and execute arbitrary code on the system with the victim's privileges.
